impl Eq for J2kCodec

impl ImageCodec for J2kCodec

type Error = J2kError

Codec-specific error type.

type Warning = Infallible

Non-fatal warning type returned in successful decode outcomes.

type Pool = J2kScratchPool

Caller-owned scratch pool type used to reuse allocations.

impl PartialEq for J2kCodec

fn eq(&self, other: &J2kCodec) -> bool

1.0.0 (const: unstable) · Source§

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

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