Struct binread::NullWideString

pub struct NullWideString(pub Vec<u16>);

A null terminated UTF-16 string designed to make reading any 16 bit wide null-terminated data easier.

Note: Does not include the null.

Note: This is endian dependent on a per-character basis. Will read u16s until a 0u16 is found.

Implementations

impl NullWideString

pub fn into_string(self) -> String

pub fn into_string_lossless(self) -> Result<String, FromUtf16Error>

Methods from Deref<Target = Vec<u16>>

pub fn capacity(&self) -> usize

Returns the number of elements the vector can hold without reallocating.

Examples

let vec: Vec<i32> = Vec::with_capacity(10);
assert_eq!(vec.capacity(), 10);

pub fn as_slice(&self) -> &[T]

Extracts a slice containing the entire vector.

Equivalent to &s[..].

Examples

use std::io::{self, Write};
let buffer = vec![1, 2, 3, 5, 8];
io::sink().write(buffer.as_slice()).unwrap();

pub fn as_ptr(&self) -> *const T

Returns a raw pointer to the vector's buffer.

The caller must ensure that the vector outlives the pointer this function returns, or else it will end up pointing to garbage. Modifying the vector may cause its buffer to be reallocated, which would also make any pointers to it invalid.

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 slice, use as_mut_ptr.

Examples

let x = vec![1, 2, 4];
let x_ptr = x.as_ptr();

unsafe {
    for i in 0..x.len() {
        assert_eq!(*x_ptr.add(i), 1 << i);
    }
}

pub fn len(&self) -> usize

Returns the number of elements in the vector, also referred to as its 'length'.

Examples

let a = vec![1, 2, 3];
assert_eq!(a.len(), 3);

pub fn is_empty(&self) -> bool

Returns true if the vector contains no elements.

Examples

let mut v = Vec::new();
assert!(v.is_empty());

v.push(1);
assert!(!v.is_empty());

Trait Implementations

impl BinRead for NullWideString

type Args = ()

The type of arguments needed to be supplied in order to read this type, usually a tuple.

fn read_options<R: Read + Seek>(
    reader: &mut R,
    options: &ReadOptions,
    args: Self::Args
) -> BinResult<Self>

Read the type from the reader

fn read<R: Read + Seek>(reader: &mut R) -> BinResult<Self>

    &mut self,
    _: &mut R,
    _: &ReadOptions,
    _: Self::Args
) -> BinResult<()>

fn args_default() -> Option<Self::Args>
