pub struct CoTaskMemPWSTR<'a>(_, _);
Expand description

RAII holder for a PWSTR which is allocated with Com::CoTaskMemAlloc and freed with Com::CoTaskMemFree when dropped.

Implementations§

source§

impl<'a> CoTaskMemPWSTR<'a>

source

pub fn as_mut(&'a mut self) -> CoTaskMemMut<'a>

Get a mutable PWSTR guard which borrows the pointer.

source

pub fn as_ref(&'a self) -> CoTaskMemRef<'a>

Get a constant PCWSTR guard which borrows the pointer.

source

pub fn take(&mut self) -> PWSTR

Take the PWSTR pointer and hand off ownership so that it is not freed when the CoTaskMemPWSTR is dropped.
