Required Methods§
sourcefn color_buffer_type(&self) -> Option<ColorBufferType>
fn color_buffer_type(&self) -> Option<ColorBufferType>
The type of the underlying color buffer.
None is returned when the format can not be identified.
sourcefn float_pixels(&self) -> bool
fn float_pixels(&self) -> bool
Whether the config uses floating pixels.
sourcefn alpha_size(&self) -> u8
fn alpha_size(&self) -> u8
The size of the alpha.
sourcefn depth_size(&self) -> u8
fn depth_size(&self) -> u8
The size of the depth buffer.
sourcefn stencil_size(&self) -> u8
fn stencil_size(&self) -> u8
The size of the stencil buffer.
sourcefn num_samples(&self) -> u8
fn num_samples(&self) -> u8
The number of samples in multisample buffer.
Zero would mean that there’re no samples.
sourcefn srgb_capable(&self) -> bool
fn srgb_capable(&self) -> bool
Whether the config supports creating srgb capable Surface.
sourcefn supports_transparency(&self) -> Option<bool>
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.
sourcefn hardware_accelerated(&self) -> bool
fn hardware_accelerated(&self) -> bool
Whether the config is hardware accelerated.
The meaning of this may vary from system to system. On some it could mean that you’re using a software backend renderer, it could mean that you’re using not the fastest available GPU, like in laptops with hybrid graphics.
sourcefn config_surface_types(&self) -> ConfigSurfaceTypes
fn config_surface_types(&self) -> ConfigSurfaceTypes
The type of the surfaces that can be created with this config.
sourcefn api(&self) -> Api
fn api(&self) -> Api
The crate::config::Api supported by the configuration.
