Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Vulkan(i32)

VkResult code from a Vulkan call.

V4l2(i32)

errno from a V4L2 ioctl.

Wgpu

wgpu device or queue error.

MediaFoundation(i32)

HRESULT from a Windows Media Foundation / COM call.

Cuda(i32)

CUresult code from a CUDA Driver API call.

Io(i32)

Raw OS error code from a filesystem operation (FileSrc / FileSink), zero when the OS reported none.

Alsa(i32)

ALSA snd_* return code (negative errno) from alsasink.

PulseAudio(i32)

PulseAudio error code (pa_error_code_t) from pulsesink.

PipeWire(i32)

PipeWire / SPA failure from pipewiresink / pipewiresrc; carries a negative errno where one is available, else -1.

Peripheral

MCU peripheral bus transfer failure (SPI / I2C / I2S via the embedded-hal seams in g2g-mcu). No payload: HAL error types are generic per implementation and the no_std core cannot carry them.

Other

Other backend-specific failure.
