Struct WString

Source
pub struct WString(/* private fields */);
Expand description

WString is the utf16 string, similar to std::wstring in cpp. It is used for passing utf16 string buffers between Rust and COM.

Implementations§

Source§

impl WString

Source

pub const fn new() -> WString

creates an empty string

Source

pub const fn is_empty(&self) -> bool

returns if the string is empty

Source

pub fn len(&self) -> usize

len is the utf16 len not including the null terminator bytes

Source

pub fn as_wide(&self) -> &[u16]

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

Source

pub fn to_string_lossy(&self) -> String

Get the contents of this WString as a String lossily.

Source

pub fn as_ptr(&self) -> *const u16

Returns a raw pointer to the WString buffer.

Source

pub fn as_pcwstr(&self) -> PCWSTR

Source

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

From slice without the null terminator.
