Struct PassthroughCandidate 

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

A borrowed compressed frame/tile that may be copied unchanged.

Implementations

impl<'a> PassthroughCandidate<'a>

pub const fn new( bytes: &'a [u8], transfer_syntax: CompressedTransferSyntax, payload_kind: CompressedPayloadKind, info: Info, ) -> PassthroughCandidate<'a>

Construct a candidate from already-inspected compressed bytes.

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

Original compressed bytes. A successful passthrough decision returns this exact slice.

pub const fn transfer_syntax(&self) -> CompressedTransferSyntax

Source compressed syntax.

pub const fn payload_kind(&self) -> CompressedPayloadKind

Source payload/container shape.

pub const fn info(&self) -> &Info

Header metadata inspected from the compressed payload.

pub fn evaluate( &self, requirements: &PassthroughRequirements, ) -> PassthroughDecision<'a>

Evaluate whether this candidate can be copied unchanged into a destination with the supplied requirements.

pub fn copy_bytes_if_eligible( &self, requirements: &PassthroughRequirements, ) -> Result<&'a [u8], PassthroughRejectReason>

Return the original compressed bytes only when passthrough is legal.

Trait Implementations

impl<'a> Clone for PassthroughCandidate<'a>

fn clone(&self) -> PassthroughCandidate<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for PassthroughCandidate<'a>

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

Formats the value using the given formatter.

impl<'a> Eq for PassthroughCandidate<'a>

impl<'a> PartialEq for PassthroughCandidate<'a>

fn eq(&self, other: &PassthroughCandidate<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
