Struct show_image::WindowId
source · [−]pub struct WindowId(_);
Expand description
Identifier of a window. Unique for each window.
Can be obtained with window.id()
.
Whenever you receive an event specific to a window, this event contains a WindowId
which you
can then compare to the ids of your windows.
Implementations
sourceimpl WindowId
impl WindowId
sourcepub const unsafe fn dummy() -> WindowId
pub const unsafe fn dummy() -> WindowId
Returns a dummy WindowId
, useful for unit testing.
Safety
The only guarantee made about the return value of this function is that
it will always be equal to itself and to future values returned by this function.
No other guarantees are made. This may be equal to a real WindowId
.
Passing this into a winit function will result in undefined behavior.
