Struct compeg::DecodeOp

pub struct DecodeOp<'a> { /* private fields */ }

Information about an ongoing JPEG decode operation.

Returned by Decoder::start_decode.

Implementations

impl<'a> DecodeOp<'a>

pub fn submission(&self) -> &SubmissionIndex

Returns the SubmissionIndex associated with the compute shader dispatch.

pub fn texture(&self) -> &Texture

Returns a reference to the target Texture that the JPEG decode operation is writing to.

Note that, when using the Decoder with JPEG images of varying sizes, not the entire target texture will be written to. The caller has to ensure to only use the area of the Texture indicated by ImageData::width and ImageData::height.

pub fn texture_changed(&self) -> bool

Returns a bool indicating whether the target Texture has been reallocated since the last decode operation on the same Decoder was started.

If this is the first decode operation, this method will return true. The return value of this method can be used to determine whether any bind groups referencing the target Texture need to be recreated.
