}

Tile-batch helpers that queue device submissions.

Required Associated Types

type Context: CodecContext

Codec-specific context cached across tiles.

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_tile_to_device( ctx: &mut DecoderContext<Self::Context>, session: &mut Self::Session, pool: &mut Self::Pool, input: &[u8], fmt: PixelFormat, backend: BackendRequest, ) -> Result<Self::SubmittedSurface, Self::Error>

Submit one full tile to the requested backend.

Errors

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

fn submit_tile_region_to_device( ctx: &mut DecoderContext<Self::Context>, session: &mut Self::Session, pool: &mut Self::Pool, input: &[u8], fmt: PixelFormat, roi: Rect, backend: BackendRequest, ) -> Result<Self::SubmittedSurface, Self::Error>

Submit one tile region 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_tile_scaled_to_device( ctx: &mut DecoderContext<Self::Context>, session: &mut Self::Session, pool: &mut Self::Pool, input: &[u8], fmt: PixelFormat, scale: Downscale, backend: BackendRequest, ) -> Result<Self::SubmittedSurface, Self::Error>

Submit one tile at reduced resolution 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_tile_region_scaled_to_device( ctx: &mut DecoderContext<Self::Context>, session: &mut Self::Session, pool: &mut Self::Pool, request: TileRegionScaledDeviceDecodeRequest<'_>, ) -> Result<Self::SubmittedSurface, Self::Error>

Submit one tile region at reduced resolution to the requested backend.

Errors

Returns the codec-specific ImageCodec::Error when the 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".
