pub struct U16CStr { /* private fields */ }
Expand description

C-style 16-bit wide string slice for U16CString.

U16CStr is to U16CString as CStr is to CString.

U16CStr are string slices that do not have a defined encoding. While it is sometimes assumed that they contain possibly invalid or ill-formed UTF-16 data, they may be used for any wide encoded string.

Nul termination

U16CStr is aware of nul (0) values. Unless unchecked conversions are used, all U16CStr strings end with a nul-terminator in the underlying buffer and contain no internal nul values. These strings are intended to be used with C FFI functions that require nul-terminated strings.

Because of the nul termination requirement, multiple classes methods for provided for construction a U16CStr under various scenarios. By default, methods such as from_ptr and from_slice return an error if the input does not terminate with a nul value, or if it contains any interior nul values before the terminator.

_truncate methods on the other hand, such as from_ptr_truncate and from_slice_truncate, construct a slice that terminates with the first nul value encountered in the string, only returning an error if the slice contains no nul values at all. Use this to mimic the behavior of C functions such as strlen when you don’t know if the input is clean of interior nuls.

Finally, unsafe _unchecked variants of these methods, such as from_ptr_unchecked and from_slice_unchecked allow bypassing any checks for nul values, when the input has already been ensured to have a nul terminator and no interior nul values.

Examples

The easiest way to use U16CStr outside of FFI is with the u16cstr! macro to convert string literals into nul-terminated UTF-16 string slices at compile time:

use widestring::u16cstr;
let hello = u16cstr!("Hello, world!");

You can also convert any u16 slice directly, as long as it has a nul terminator:

use widestring::{u16cstr, U16CStr};

let sparkle_heart = [0xd83d, 0xdc96, 0x0];
let sparkle_heart = U16CStr::from_slice(&sparkle_heart).unwrap();

assert_eq!(u16cstr!("💖"), sparkle_heart);

// This unpaired UTf-16 surrogate is invalid UTF-16, but is perfectly valid in U16CStr
let malformed_utf16 = [0xd83d, 0x0];
let s = U16CStr::from_slice(&malformed_utf16).unwrap();

assert_eq!(s.len(), 1);

When working with a FFI, it is useful to create a U16CStr from a pointer:

use widestring::{u16cstr, U16CStr};

let sparkle_heart = [0xd83d, 0xdc96, 0x0];
let s = unsafe {
    // Note the string and pointer length does not include the nul terminator
    U16CStr::from_ptr(sparkle_heart.as_ptr(), sparkle_heart.len() - 1).unwrap()
};
assert_eq!(u16cstr!("💖"), s);

// Alternatively, if the length of the pointer is unknown but definitely terminates in nul,
// a C-style string version can be used
let s = unsafe { U16CStr::from_ptr_str(sparkle_heart.as_ptr()) };

assert_eq!(u16cstr!("💖"), s);

Implementations

The nul terminator character value.

Coerces a value into a wide C string slice.

Constructs a wide C string slice from a nul-terminated string pointer.

This will scan for nul values beginning with p. The first nul value will be used as the nul terminator for the string, similar to how libc string functions such as strlen work.

Safety

This function is unsafe as there is no guarantee that the given pointer is valid or has a nul terminator, and the function could scan past the underlying buffer.

In addition, the data must meet the safety conditions of std::slice::from_raw_parts. In particular, the returned string reference must not be mutated for the duration of lifetime 'a, except inside an UnsafeCell.

Panics

This function panics if p is null.

Caveat

The lifetime for the returned string is inferred from its usage. To prevent accidental misuse, it’s suggested to tie the lifetime to whichever source lifetime is safe in the context, such as by providing a helper function taking the lifetime of a host value for the string, or by explicit annotation.

Constructs a mutable wide C string slice from a mutable nul-terminated string pointer.

This will scan for nul values beginning with p. The first nul value will be used as the nul terminator for the string, similar to how libc string functions such as strlen work.

Safety

This function is unsafe as there is no guarantee that the given pointer is valid or has a nul terminator, and the function could scan past the underlying buffer.

In addition, the data must meet the safety conditions of std::slice::from_raw_parts_mut.

Panics

This function panics if p is null.

Caveat

The lifetime for the returned string is inferred from its usage. To prevent accidental misuse, it’s suggested to tie the lifetime to whichever source lifetime is safe in the context, such as by providing a helper function taking the lifetime of a host value for the string, or by explicit annotation.

Constructs a wide C string slice from a pointer and a length.

The len argument is the number of elements, not the number of bytes, and does not include the nul terminator of the string. Thus, a len of 0 is valid and means that p is a pointer directly to the nul terminator of the string.

Errors

This will scan the pointer string for an interior nul value and error if one is found before the nul terminator at len offset. To avoid scanning for interior nuls, from_ptr_unchecked may be used instead.

An error is returned if the value at len offset is not a nul terminator.

Safety

This function is unsafe as there is no guarantee that the given pointer is valid for len + 1 elements.

In addition, the data must meet the safety conditions of std::slice::from_raw_parts. In particular, the returned string reference must not be mutated for the duration of lifetime 'a, except inside an UnsafeCell.

Panics

To prevent accidental misuse, it’s suggested to tie the lifetime to whichever source lifetime is safe in the context, such as by providing a helper function taking the lifetime of a host value for the string, or by explicit annotation.

Constructs a mutable wide C string slice from a mutable pointer and a length.

The len argument is the number of elements, not the number of bytes, and does not include the nul terminator of the string. Thus, a len of 0 is valid and means that p is a pointer directly to the nul terminator of the string.

Errors

This will scan the pointer string for an interior nul value and error if one is found before the nul terminator at len offset. To avoid scanning for interior nuls, from_ptr_unchecked_mut may be used instead.

An error is returned if the value at len offset is not a nul terminator.

Safety

This function is unsafe as there is no guarantee that the given pointer is valid for len + 1 elements.

In addition, the data must meet the safety conditions of std::slice::from_raw_parts_mut.

To prevent accidental misuse, it’s suggested to tie the lifetime to whichever source lifetime is safe in the context, such as by providing a helper function taking the lifetime of a host value for the string, or by explicit annotation.

Constructs a wide C string slice from a pointer and a length, truncating at the first nul terminator.

The len argument is the number of elements, not the number of bytes. This will scan for nul values beginning with p until offset len. The first nul value will be used as the nul terminator for the string, ignoring any remaining values left before len.

Errors

If no nul terminator is found after len + 1 elements, an error is returned.

Safety

This function is unsafe as there is no guarantee that the given pointer is valid or has a nul terminator, and the function could scan past the underlying buffer.

Constructs a wide C string slice from a pointer and a length without checking for any nul values.

The len argument is the number of elements, not the number of bytes, and does not include the nul terminator of the string. Thus, a len of 0 is valid and means that p is a pointer directly to the nul terminator of the string.

Safety

This function is unsafe as there is no guarantee that the given pointer is valid for len + 1 elements, nor that it has a terminating nul value.

In addition, the data must meet the safety conditions of std::slice::from_raw_parts. In particular, the returned string reference must not be mutated for the duration of lifetime 'a, except inside an UnsafeCell.

The interior values of the pointer are not scanned for nul. Any interior nul values or a missing nul terminator at pointer offset len + 1 will result in an invalid string slice.

Constructs a wide C string slice from a slice of values with a terminating nul, checking for invalid interior nul values.

The slice must have at least one item, the nul terminator, even for an empty string.

Errors

If there are nul values in the slice except for the last value, an error is returned.

An error is also returned if the last value of the slice is not a nul terminator.

Constructs a mutable wide C string slice from a mutable slice of values with a terminating nul, checking for invalid interior nul values.

The slice must have at least one item, the nul terminator, even for an empty string.

Errors

If there are nul values in the slice except for the last value, an error is returned.

An error is also returned if the last value of the slice is not a nul terminator.

Constructs a wide C string slice from a slice of values, truncating at the first nul terminator.

The slice will be scanned for nul values. When a nul value is found, it is treated as the terminator for the string, and the string slice will be truncated to that nul.

Errors

If there are no nul values in the slice, an error is returned.

Constructs a mutable wide C string slice from a mutable slice of values, truncating at the first nul terminator.

The slice will be scanned for nul values. When a nul value is found, it is treated as the terminator for the string, and the string slice will be truncated to that nul.

Errors

If there are no nul values in the slice, an error is returned.

Constructs a wide C string slice from a slice of values without checking for a terminating or interior nul values.

Safety

This function is unsafe because it can lead to invalid string slice values when the slice is missing a terminating nul value or there are non-terminating interior nul values in the slice. In particular, an empty slice will result in an invalid string slice.

Constructs a mutable wide C string slice from a mutable slice of values without checking for a terminating or interior nul values.

Safety

This function is unsafe because it can lead to invalid string slice values when the slice is missing a terminating nul value or there are non-terminating interior nul values in the slice. In particular, an empty slice will result in an invalid string slice.

Copies the string reference to a new owned wide C string.

Copies the string reference to a new owned wide string.

The resulting wide string will not have a nul terminator.

Examples
use widestring::U16CString;
let wcstr = U16CString::from_str("MyString").unwrap();
// Convert U16CString to a U16String
let wstr = wcstr.to_ustring();

// U16CString will have a terminating nul
let wcvec = wcstr.into_vec_with_nul();
assert_eq!(wcvec[wcvec.len()-1], 0);
// The resulting U16String will not have the terminating nul
let wvec = wstr.into_vec();
assert_ne!(wvec[wvec.len()-1], 0);

Converts to a slice of the underlying elements.

The slice will not include the nul terminator.

Converts to a mutable slice of the underlying elements.

The slice will not include the nul terminator.

Safety

This method is unsafe because you can violate the invariants of this type when mutating the slice (i.e. by adding interior nul values).

Converts to a slice of the underlying elements, including the nul terminator.

Returns a raw pointer to the string.

The caller must ensure that the string outlives the pointer this function returns, or else it will end up pointing to garbage.

The caller must also ensure that the memory the pointer (non-transitively) points to is never written to (except inside an UnsafeCell) using this pointer or any pointer derived from it. If you need to mutate the contents of the string, use as_mut_ptr.

Modifying the container referenced by this string may cause its buffer to be reallocated, which would also make any pointers to it invalid.

Returns a mutable raw pointer to the string.

The caller must ensure that the string outlives the pointer this function returns, or else it will end up pointing to garbage.

Modifying the container referenced by this string may cause its buffer to be reallocated, which would also make any pointers to it invalid.

Returns the two raw pointers spanning the string slice.

The returned range is half-open, which means that the end pointer points one past the last element of the slice. This way, an empty slice is represented by two equal pointers, and the difference between the two pointers represents the size of the slice.

See as_ptr for warnings on using these pointers. The end pointer requires extra caution, as it does not point to a valid element in the slice.

This function is useful for interacting with foreign interfaces which use two pointers to refer to a range of elements in memory, as is common in C++.

Returns the two unsafe mutable pointers spanning the string slice.

The returned range is half-open, which means that the end pointer points one past the last element of the slice. This way, an empty slice is represented by two equal pointers, and the difference between the two pointers represents the size of the slice.

This function is useful for interacting with foreign interfaces which use two pointers to refer to a range of elements in memory, as is common in C++.

Returns the length of the string as number of elements (not number of bytes) not including nul terminator.

Returns whether this string contains no data (i.e. is only the nul terminator).

Converts a boxed wide C string slice into an wide C string without copying or allocating.

Examples
use widestring::U16CString;

let v = vec![102u16, 111u16, 111u16]; // "foo"
let c_string = U16CString::from_vec(v.clone()).unwrap();
let boxed = c_string.into_boxed_ucstr();
assert_eq!(boxed.into_ucstring(), U16CString::from_vec(v).unwrap());

Returns a wide string slice to this wide C string slice.

The wide string slice will not include the nul-terminator.

Returns a wide string slice to this wide C string slice.

The wide string slice will include the nul-terminator.

Returns a mutable wide string slice to this wide C string slice.

The wide string slice will not include the nul-terminator.

Safety

This method is unsafe because you can violate the invariants of this type when mutating the string (i.e. by adding interior nul values).

Returns an object that implements Display for printing strings that may contain non-Unicode data.

A wide C string might data of any encoding. This function assumes the string is encoded in UTF-16, and returns a struct implements the Display trait in a way that decoding the string is lossy but no heap allocations are performed, such as by to_string_lossy.

By default, invalid Unicode data is replaced with U+FFFD REPLACEMENT CHARACTER (�). If you wish to simply skip any invalid Uncode data and forego the replacement, you may use the alternate formatting with {:#}.

Examples

Basic usage:

use widestring::U16CStr;

// 𝄞mus<invalid>ic<invalid>
let s = U16CStr::from_slice(&[
    0xD834, 0xDD1E, 0x006d, 0x0075, 0x0073, 0xDD1E, 0x0069, 0x0063, 0xD834, 0x0000,
]).unwrap();

assert_eq!(format!("{}", s.display()),
"𝄞mus�ic�"
);

Using alternate formatting style to skip invalid values entirely:

use widestring::U16CStr;

// 𝄞mus<invalid>ic<invalid>
let s = U16CStr::from_slice(&[
    0xD834, 0xDD1E, 0x006d, 0x0075, 0x0073, 0xDD1E, 0x0069, 0x0063, 0xD834, 0x0000,
]).unwrap();

assert_eq!(format!("{:#}", s.display()),
"𝄞music"
);

Returns a subslice of the string.

This is the non-panicking alternative to indexing the string. Returns None whenever equivalent indexing operation would panic.

Returns a mutable subslice of the string.

This is the non-panicking alternative to indexing the string. Returns None whenever equivalent indexing operation would panic.

Safety

This method is unsafe because you can violate the invariants of this type when mutating the memory the pointer points to (i.e. by adding interior nul values).

Returns an unchecked subslice of the string.

This is the unchecked alternative to indexing the string.

Safety

Callers of this function are responsible that these preconditions are satisfied:

  • The starting index must not exceed the ending index;
  • Indexes must be within bounds of the original slice.

Failing that, the returned string slice may reference invalid memory.

Returns aa mutable, unchecked subslice of the string.

This is the unchecked alternative to indexing the string.

This method is unsafe because you can violate the invariants of this type when mutating the memory the pointer points to (i.e. by adding interior nul values).

Divide one string slice into two at an index.

The argument, mid, should be an offset from the start of the string.

The two slices returned go from the start of the string slice to mid, and from mid to the end of the string slice.

To get mutable string slices instead, see the split_at_mut method.

Creates a new owned string by repeating this string n times.

Panics

This function will panic if the capacity would overflow.

Copys a string to an owned OsString.

This makes a string copy of the U16CStr. Since U16CStr makes no guarantees that it is valid UTF-16, there is no guarantee that the resulting OsString will be valid data. The OsString will not have a nul terminator.

Note that the encoding of OsString is platform-dependent, so on some platforms this may make an encoding conversions, while on other platforms (such as windows) no changes to the string will be made.

Examples
use widestring::U16CString;
use std::ffi::OsString;
let s = "MyString";
// Create a wide string from the string
let wstr = U16CString::from_str(s).unwrap();
// Create an OsString from the wide string
let osstr = wstr.to_os_string();

assert_eq!(osstr, OsString::from(s));

Copies the string to a String if it contains valid UTF-16 data.

This method assumes this string is encoded as UTF-16 and attempts to decode it as such. It will *not have a nul terminator.

Errors

Returns an error if the string contains any invalid UTF-16 data.

Examples
use widestring::U16CString;
let s = "MyString";
// Create a wide string from the string
let wstr = U16CString::from_str(s).unwrap();
// Create a regular string from the wide string
let s2 = wstr.to_string().unwrap();

assert_eq!(s2, s);

Decodes the string reference to a String even if it is invalid UTF-16 data.

This method assumes this string is encoded as UTF-16 and attempts to decode it as such. Any invalid sequences are replaced with U+FFFD REPLACEMENT CHARACTER, which looks like this: �. It will *not have a nul terminator.

Examples
use widestring::U16CString;
let s = "MyString";
// Create a wide string from the string
let wstr = U16CString::from_str(s).unwrap();
// Create a regular string from the wide string
let s2 = wstr.to_string_lossy();

assert_eq!(s2, s);

Returns an iterator over the chars of a string slice.

As this string has no defined encoding, this method assumes the string is UTF-16. Since it may consist of invalid UTF-16, the iterator returned by this method is an iterator over Result<char, DecodeUtf16Error> instead of chars directly. If you would like a lossy iterator over charss directly, instead use chars_lossy.

It’s important to remember that char represents a Unicode Scalar Value, and may not match your idea of what a ‘character’ is. Iteration over grapheme clusters may be what you actually want. That functionality is not provided by by this crate.

Returns a lossy iterator over the chars of a string slice.

As this string has no defined encoding, this method assumes the string is UTF-16. Since it may consist of invalid UTF-16, the iterator returned by this method will replace unpaired surrogates with U+FFFD REPLACEMENT CHARACTER (�). This is a lossy version of chars.

Returns an iterator over the chars of a string slice, and their positions.

As this string has no defined encoding, this method assumes the string is UTF-16. Since it may consist of invalid UTF-16, the iterator returned by this method is an iterator over is an iterator over Result<char, DecodeUtf16Error> as well as their positions, instead of chars directly. If you would like a lossy indices iterator over charss directly, instead use char_indices_lossy.

The iterator yields tuples. The position is first, the char is second.
