Struct JpegView 

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

A parsed borrowed view of a JPEG stream.

Implementations

impl<'a> JpegView<'a>

pub fn parse(input: &'a [u8]) -> Result<Self, JpegError>

Parse the stream into a borrowed view that can later build a decoder.

pub fn parse_with_options( input: &'a [u8], options: DecodeOptions, ) -> Result<Self, JpegError>

Parse the stream with explicit decode options.

pub fn info(&self) -> &Info

Header-derived metadata for the parsed stream.

pub fn bytes(&self) -> &'a [u8]

Original compressed bytes backing this view.

pub fn passthrough_candidate(&self) -> Option<PassthroughCandidate<'a>>

Return a byte-preserving passthrough candidate for active DICOM/WSI transfer syntaxes.

Progressive JPEG is intentionally not exposed here because the active conversion path should transcode it rather than introduce a retired or unsupported destination syntax.

pub fn restart_index(&self) -> Result<Option<RestartIndex>, JpegError>

Build a restart-marker byte-offset index for the first scan.

Offsets are absolute byte positions in the original JPEG byte slice. Returns Ok(None) when the stream has no non-zero DRI marker.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
