Methods

impl CompressedFormat

pub fn get_formats_list() -> Vec<CompressedFormat>

Returns a list of all the possible values of this enumeration.

pub fn to_texture_format(self) -> TextureFormat

Turns this format into a more generic TextureFormat.

pub fn is_supported<C: ?Sized>(&self, context: &C) -> bool where
    C: CapabilitiesSource, 

Returns true if this format is supported by the backend.
