DeviceErrorState

Struct DeviceErrorState 

Source
pub struct DeviceErrorState { /* private fields */ }
Expand description

Errors reported by wgpu’s device-wide callbacks.

A device has exactly one lost callback and one uncaptured-error callback, so this state is installed once per device and shared by every renderer using it. Renderers keep their own handle so they can keep observing a loss after the context that produced it has been dropped for recovery.

Implementations§

Source§

impl DeviceErrorState

Source

pub fn device_lost(&self) -> bool

Returns true if the GPU device was lost (e.g., due to driver crash, suspend/resume).

Source

pub fn observe_error(&self, generation: &mut u64) -> Option<String>

Returns the latest error once per observer, without consuming shared state. Start each observer at zero, including after switching devices, so errors raised during construction are observed. Multiple errors between observations coalesce into the latest error; this is not an error queue.
