Required Methods

fn color_buffer_type(&self) -> Option<ColorBufferType>

The type of the underlying color buffer.

None is returned when the format can not be identified.

fn float_pixels(&self) -> bool

Whether the config uses floating pixels.

fn alpha_size(&self) -> u8

The size of the alpha.

fn depth_size(&self) -> u8

The size of the depth buffer.

fn stencil_size(&self) -> u8

The size of the stencil buffer.

fn num_samples(&self) -> u8

The number of samples in multisample buffer.

Zero would mean that there’re no samples.

fn srgb_capable(&self) -> bool

Whether the config supports creating srgb capable Surface.

fn supports_transparency(&self) -> Option<bool>

Whether the config supports creating transparent surfaces.

This function will return None when the property couldn’t be identified, in that case transparent window could still work.

fn config_surface_types(&self) -> ConfigSurfaceTypes

The type of the surfaces that can be created with this config.

fn api(&self) -> Api

The crate::config::Api supported by the configuration.
