Expand description

A container for owned byte strings converted by this crate.

Implementations

source

impl RawOsString

source

pub fn new(string: OsString) -> RawOsString

Converts a platform-native string into a representation that can be more easily manipulated.

For more information, see RawOsStr::new.

Examples

use std::env;

use os_str_bytes::RawOsString;

let os_string = env::current_exe()?.into_os_string();
println!("{:?}", RawOsString::new(os_string));

source

pub fn from_string(string: String) -> RawOsString

Wraps a string, without copying or encoding conversion.

This method is much more efficient than RawOsString::new, since the encoding used by this crate is compatible with UTF-8.

Examples

use os_str_bytes::RawOsString;

let string = "foobar".to_owned();
let raw = RawOsString::from_string(string.clone());
assert_eq!(string, raw);

source

pub fn assert_from_raw_vec(string: Vec<u8, Global>) -> RawOsString

Wraps a byte string, without copying or encoding conversion.

Panics

Panics if the string is not valid for the unspecified encoding used by this crate.

Examples

use std::env;

use os_str_bytes::RawOsString;

let os_string = env::current_exe()?.into_os_string();
let raw = RawOsString::new(os_string);
let raw_bytes = raw.clone().into_raw_vec();
assert_eq!(raw, RawOsString::assert_from_raw_vec(raw_bytes));

source

pub unsafe fn from_raw_vec_unchecked(string: Vec<u8, Global>) -> RawOsString

Wraps a byte string, without copying or encoding conversion.

Safety

The string must be valid for the unspecified encoding used by this crate.

Examples

use std::env;

use os_str_bytes::RawOsString;

let os_string = env::current_exe()?.into_os_string();
let raw = RawOsString::new(os_string);
let raw_bytes = raw.clone().into_raw_vec();
assert_eq!(raw, unsafe {
    RawOsString::from_raw_vec_unchecked(raw_bytes)
});

source

pub fn clear(&mut self)

Equivalent to String::clear.

Examples

use std::env;

use os_str_bytes::RawOsString;

let os_string = env::current_exe()?.into_os_string();
let mut raw = RawOsString::new(os_string);
raw.clear();
assert!(raw.is_empty());

source

pub fn into_box(self) -> Box<RawOsStr, Global>

Equivalent to String::into_boxed_str.

Examples

use os_str_bytes::RawOsString;

let string = "foobar".to_owned();
let raw = RawOsString::from_string(string.clone());

Converts this representation back to a platform-native string.

Examples

use std::env;

use os_str_bytes::RawOsString;

let os_string = env::current_exe()?.into_os_string();
let raw = RawOsString::new(os_string.clone());
assert_eq!(os_string, raw.into_os_string());

source

pub fn into_raw_vec(self) -> Vec<u8, Global>

The returned string will use an unspecified encoding.

Examples

assert_eq!(string.into_bytes(), raw.into_raw_vec());

source

pub fn into_string(self) -> Result<String, RawOsString>

Equivalent to OsString::into_string.

Examples

use os_str_bytes::RawOsString;

let string = "foobar".to_owned();
let raw = RawOsString::from_string(string.clone());
assert_eq!(Ok(string), raw.into_string());

source

pub fn shrink_to_fit(&mut self)

Equivalent to String::shrink_to_fit.

Examples

use os_str_bytes::RawOsString;

let string = "foobar".to_owned();

raw.shrink_to_fit();
assert_eq!(string, raw);

source

pub fn split_off(&mut self, at: usize) -> RawOsString

Equivalent to String::split_off.

Panics

Panics if the index is not a valid boundary.

assert_eq!("foo", raw);

source

pub fn truncate(&mut self, new_len: usize)

Equivalent to String::truncate.

Panics

Panics if the index is not a valid boundary.

Examples

use os_str_bytes::RawOsString;

let mut raw = RawOsString::from_string("foobar".to_owned());
raw.truncate(3);
assert_eq!("foo", raw);

Methods from Deref<Target = RawOsStr>

source

pub fn as_raw_bytes(&self) -> &[u8]ⓘNotable traits for &[u8]`impl Read for &[u8]impl Write for &mut [u8]`

Returns the byte string stored by this container.

The returned string will use an unspecified encoding.

Examples

use os_str_bytes::RawOsStr;

let string = "foobar";
let raw = RawOsStr::from_str(string);
assert_eq!(string.as_bytes(), raw.as_raw_bytes());

source

pub fn contains(&self, pat: P) -> boolwhere
P: Pattern,

Equivalent to str::contains.

Examples

use os_str_bytes::RawOsStr;

let raw = RawOsStr::from_str("foobar");
assert!(raw.contains("oo"));
assert!(!raw.contains("of"));

source

pub fn ends_with(&self, pat: P) -> boolwhere
P: Pattern,

Equivalent to str::ends_with.

Examples

use os_str_bytes::RawOsStr;

let raw = RawOsStr::from_str("foobar");
assert!(raw.ends_with("bar"));
assert!(!raw.ends_with("foo"));

source

pub fn ends_with_os(&self, pat: &RawOsStr) -> bool

Equivalent to str::ends_with but accepts this type for the pattern.

Examples

use os_str_bytes::RawOsStr;

let raw = RawOsStr::from_str("foobar");
assert!(raw.ends_with_os(RawOsStr::from_str("bar")));
assert!(!raw.ends_with_os(RawOsStr::from_str("foo")));

source

pub fn find(&self, pat: P) -> Option<usize>where
P: Pattern,

Equivalent to str::find.

Examples

use os_str_bytes::RawOsStr;

let raw = RawOsStr::from_str("foobar");
assert_eq!(Some(1), raw.find("o"));
assert_eq!(None, raw.find("of"));

source

pub fn is_empty(&self) -> bool

Equivalent to str::is_empty.

Examples

use os_str_bytes::RawOsStr;

assert!(RawOsStr::from_str("").is_empty());
assert!(!RawOsStr::from_str("foobar").is_empty());

source

pub fn raw_len(&self) -> usize

Returns the length of the byte string stored by this container.

Only the following assumptions can be made about the result:

The length of any Unicode character is the length of its UTF-8 representation (i.e., char::len_utf8).
Splitting a string at a UTF-8 boundary will return two strings with lengths that sum to the length of the original string.

This method may return a different result than would OsStr::len when called on same string, since OsStr uses an unspecified encoding.

Examples

use os_str_bytes::RawOsStr;

assert_eq!(6, RawOsStr::from_str("foobar").raw_len());
assert_eq!(0, RawOsStr::from_str("").raw_len());

source

pub fn rfind(&self, pat: P) -> Option<usize>where
P: Pattern,

assert_eq!(None, raw.rfind("of"));

source

pub fn rsplit_once(&self, pat: P) -> Option<(&RawOsStr, &RawOsStr)>where
P: Pattern,

Equivalent to str::rsplit_once.

Examples

use os_str_bytes::RawOsStr;

let raw = RawOsStr::from_str("foobar");

Converts this representation back to a platform-native string.

When possible, use RawOsStrCow::into_os_str for a more efficient conversion on some platforms.

Examples

use std::env;

use os_str_bytes::RawOsStr;

let os_string = env::current_exe()?.into_os_string();

source

pub fn trim_start_matches(&self, pat: P) -> &RawOsStrwhere
P: Pattern,

Equivalent to str::trim_start_matches.

Examples

use os_str_bytes::RawOsStr;

let raw = RawOsStr::from_str("111foo1bar111");
assert_eq!("foo1bar111", raw.trim_start_matches("1"));
assert_eq!("111foo1bar111", raw.trim_start_matches("o"));
