Stateless tile-batch decode helpers that reuse caller-owned context.

Required Associated Types

type Context: CodecContext

Codec-specific context cached across tiles.

Required Methods

fn decode_tile<'a>( ctx: &mut DecoderContext<Self::Context>, pool: &mut Self::Pool, input: &'a [u8], out: &mut [u8], stride: usize, fmt: PixelFormat, ) -> Result<DecodeOutcome<Self::Warning>, Self::Error>

Decode one tile into caller-owned output.

fn decode_tile_region<'a>( ctx: &mut DecoderContext<Self::Context>, pool: &mut Self::Pool, input: &'a [u8], out: &mut [u8], stride: usize, fmt: PixelFormat, roi: Rect, ) -> Result<DecodeOutcome<Self::Warning>, Self::Error>

Decode one tile region into caller-owned output.

fn decode_tile_scaled<'a>( ctx: &mut DecoderContext<Self::Context>, pool: &mut Self::Pool, input: &'a [u8], out: &mut [u8], stride: usize, fmt: PixelFormat, scale: Downscale, ) -> Result<DecodeOutcome<Self::Warning>, Self::Error>

Decode one tile at reduced resolution into caller-owned output.

fn decode_tile_region_scaled<'a>( ctx: &mut DecoderContext<Self::Context>, pool: &mut Self::Pool, input: &'a [u8], out: &mut [u8], stride: usize, fmt: PixelFormat, roi: Rect, scale: Downscale, ) -> Result<DecodeOutcome<Self::Warning>, Self::Error>

Decode one tile region at reduced resolution into caller-owned output.

Provided Methods

fn decode_tile_request<'a>( ctx: &mut DecoderContext<Self::Context>, pool: &mut Self::Pool, input: &'a [u8], out: &mut [u8], stride: usize, fmt: PixelFormat, request: DecodeRequest, ) -> Result<DecodeOutcome<Self::Warning>, Self::Error>

Decode one tile for a normalized full/ROI/scaled request.

Dyn Compatibility

This trait is not dyn compatible.

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