Struct OffscreenTopLevelImplBase 

pub struct OffscreenTopLevelImplBase { /* private fields */ }

The base of the top-level implementations that are not backed by a window of the platform: the client size and the scaling are set by the owner, which also feeds the input and provides the surfaces.

This API is unstable.

Implementations

impl OffscreenTopLevelImplBase
