#[repr(u8)]
pub enum DeviceLostReason { Unknown = 0, Destroyed = 1, Dropped = 2, ReplacedCallback = 3, DeviceInvalid = 4, }
Expand description

Reason for “lose the device”.

Corresponds to WebGPU GPUDeviceLostReason.

Variants§

§

Unknown = 0

Triggered by driver

§

Destroyed = 1

After Device::destroy

§

Dropped = 2

After Device::drop

WebGPU does not invoke the device lost callback when the device is dropped to prevent garbage collection from being observable. In wgpu, we invoke the callback on drop to help with managing memory owned by the callback.

§

ReplacedCallback = 3

After replacing the device_lost_callback

WebGPU does not have a concept of a device lost callback, but wgpu does. wgpu guarantees that any supplied callback will be invoked exactly once before it is dropped, which helps with managing the memory owned by the callback.

§

DeviceInvalid = 4

When setting the callback, but the device is already invalid

As above, when the callback is provided, wgpu guarantees that it will eventually be called. If the device is already invalid, wgpu will call the callback immediately, with this reason.
