}

Decode API for implementations that can submit work to a device backend.

Required Associated Types

type Session: Default + Send

Mutable session state shared across submissions.

type DeviceSurface: DeviceSurface

Device surface returned by completed submissions.

type SubmittedSurface: DeviceSubmission<Output = Self::DeviceSurface, Error = Self::Error>

Submission handle type.

Required Methods

fn submit_to_device( &mut self, session: &mut Self::Session, fmt: PixelFormat, backend: BackendRequest, ) -> Result<Self::SubmittedSurface, Self::Error>

Submit full-image decode to the requested backend.

Errors

Returns the codec-specific ImageCodec::Error when the request is invalid, unsupported, or cannot be submitted.

fn submit_region_to_device( &mut self, session: &mut Self::Session, fmt: PixelFormat, roi: Rect, backend: BackendRequest, ) -> Result<Self::SubmittedSurface, Self::Error>

Submit region decode to the requested backend.

Errors

Returns the codec-specific ImageCodec::Error when the region or backend request is invalid, unsupported, or cannot be submitted.

fn submit_scaled_to_device( &mut self, session: &mut Self::Session, fmt: PixelFormat, scale: Downscale, backend: BackendRequest, ) -> Result<Self::SubmittedSurface, Self::Error>

Submit reduced-resolution decode to the requested backend.

Errors

Returns the codec-specific ImageCodec::Error when the scale or backend request is invalid, unsupported, or cannot be submitted.

fn submit_region_scaled_to_device( &mut self, session: &mut Self::Session, fmt: PixelFormat, roi: Rect, scale: Downscale, backend: BackendRequest, ) -> Result<Self::SubmittedSurface, Self::Error>

Submit region decode at reduced resolution to the requested backend.

Errors

Returns the codec-specific ImageCodec::Error when the region, scale, or backend request is invalid, unsupported, or cannot be submitted.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
