Fields

context: AdapterContext

private_caps: PrivateCapabilities

features: Features

workarounds: Workarounds

shading_language_version: Version

next_shader_id: AtomicU32

program_cache: Mutex<FastHashMap<ProgramCacheKey, Result<Arc<PipelineInner>, PipelineError>>>

es: bool

max_msaa_samples: i32

Result of gl.get_parameter_i32(glow::MAX_SAMPLES). Cached here so it doesn’t need to be queried every time texture format capabilities are requested. (this has been shown to be a significant enough overhead)
