RAII implementation for HICON
which automatically
calls
DestroyIcon
when the object goes out of scope.
Implementations§
source§impl DestroyIconGuard
impl DestroyIconGuard
sourcepub const unsafe fn new(handle: HICON) -> Self
pub const unsafe fn new(handle: HICON) -> 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.
sourcepub fn leak(&mut self) -> HICON
pub fn leak(&mut self) -> HICON
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.
