Fields

shared: Arc<AdapterShared>

features: Features

draw_fbo: Framebuffer

copy_fbo: Framebuffer

shader_clear_program: Option<ShaderClearProgram>

Shader program used to clear the screen for Workarounds::MESA_I915_SRGB_SHADER_CLEAR devices.

zero_buffer: Buffer

Keep a reasonably large buffer filled with zeroes, so that we can implement ClearBuffer of zeroes by copying from it.

temp_query_results: Mutex<Vec<u64>>

draw_buffer_count: AtomicU8

current_index_buffer: Mutex<Option<Buffer>>

Implementations

impl Queue
