Struct raw_window_handle::TrustedWindowHandle[][src]

pub struct TrustedWindowHandle { /* fields omitted */ }
Expand description

This wraps a RawWindowHandle to give it a HasRawWindowHandle impl.

The HasRawWindowHandle trait must be an unsafe trait because other unsafe code is going to rely on it to provide accurate window handle info. Since RawWindowHandle is an enum and enum fields are public, anyone could make any random RawWindowHandle value in safe code.

The solution is that you assert that you’re trusting a particular handle value by (unsafely) placing it within this wrapper struct.

Implementations

Assert that the RawWindowHandle value can be trusted.

Safety

If the value violates any of the safety outlines given in the HasRawWindowHandle trait this can lead to UB.

Read from a HasRawWindowHandle into being a trusted value.
