Struct Device

pub struct Device { /* private fields */ }

Available on gles only.

Implementations

impl Device

pub fn context(&self) -> &AdapterContext

Available on neither Windows nor webgl.

Returns the underlying EGL context.

impl Device

pub unsafe fn texture_from_raw( &self, name: NonZeroU32, desc: &TextureDescriptor<'_>, drop_callback: Option<DropCallback>, ) -> Texture

Available on native or Emscripten only.

Safety

• name must be created respecting desc
• name must be a texture
• If drop_callback is None, wgpu-hal will take ownership of the texture. If drop_callback is Some, the texture must be valid until the callback is called.

pub unsafe fn texture_from_raw_renderbuffer( &self, name: NonZeroU32, desc: &TextureDescriptor<'_>, drop_callback: Option<DropCallback>, ) -> Texture

Available on native or Emscripten only.

Safety

• name must be created respecting desc
• name must be a renderbuffer
• If drop_callback is None, wgpu-hal will take ownership of the renderbuffer. If drop_callback is Some, the renderbuffer must be valid until the callback is called.
