Enum rerun::external::eframe::egui_wgpu::wgpu::DeviceLostReason

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

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.

Trait Implementations

impl Clone for DeviceLostReason

fn clone(&self) -> DeviceLostReason

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DeviceLostReason

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for DeviceLostReason

fn eq(&self, other: &DeviceLostReason) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
