Struct windows_core::BSTR

pub struct BSTR(/* private fields */);

Expand description

A BSTR string (BSTR) is a length-prefixed wide string.

Implementations§

impl BSTR

pub const fn new() -> BSTR

Create an empty BSTR.

This function does not allocate memory.

pub fn is_empty(&self) -> bool

Returns true if the string is empty.

pub fn len(&self) -> usize

Returns the length of the string.

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

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

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

Returns a raw pointer to the BSTR buffer.

pub fn from_wide(value: &[u16]) -> Result<BSTR, Error>

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

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
