Required Associated Types

type Header

type Decoder: RasterDecoder<R>

type Error

type NextPageFuture: Future<Output = Result<Option<Self>, Self::Error>>

Required Methods

fn next_page(self) -> Self::NextPageFuture

fn header(&self) -> &Self::Header

fn content_mut(&mut self) -> &mut Self::Decoder

fn into_content(self) -> Self::Decoder

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
