Struct winsafe::guard::EndDeferWindowPosGuard

source ·
pub struct EndDeferWindowPosGuard { /* private fields */ }
Available on crate features kernel and user only.
Expand description

RAII implementation for HDWP which automatically calls EndDeferWindowPos when the object goes out of scope.

Implementations§

source§

impl EndDeferWindowPosGuard

source

pub const unsafe fn new(handle: HDWP) -> Self

Constructs the guard by taking ownership of the handle.

This method can be used as an escape hatch to interoperate with other libraries.

§Safety

Be sure the handle must be freed with the specified function at the end of scope.

source

pub fn leak(&mut self) -> HDWP

Ejects the underlying handle, leaving a Handle::INVALID in its place.

Since the internal handle will be invalidated, the destructor will not run. It’s your responsability to run it, otherwise you’ll cause a resource leak.
