Struct windows::HSTRING[−][src]

#[repr(transparent)]
pub struct HSTRING(_);
Expand description

A WinRT string, sometimes called an HSTRING, is reference-counted and logically immutable. It should only be used for communicating with WinRT APIs.

Implementations

impl HSTRING[src]

pub fn new() -> Self[src]

Create an empty HSTRING.

This function does no allocation.

pub fn is_empty(&self) -> bool[src]

Returns true if the string is empty.

pub fn len(&self) -> usize[src]

Returns the length of self.

pub fn as_wide(&self) -> &[u16]ⓘ

Notable traits for &'_ [u8]

impl<'_> Read for &'_ [u8]impl<'_> Write for &'_ mut [u8]
[src]

Get the string as 16-bit wide characters (wchars).

pub fn from_wide(value: &[u16]) -> Self[src]

Create a HSTRING from a slice of 16 bit characters (wchars).

pub fn to_string_lossy(&self) -> String[src]

Get the contents of this HSTRING as a String lossily.

pub fn clear(&mut self)[src]

Clear the contents of the string and free the memory if self holds the last reference to the string data.
