Required Methods§

fn full_data(&self) -> &[u8] ⓘ

Source

fn remaining_data(&self) -> &[u8] ⓘ

Source

fn position(&self) -> usize

Source

fn advance(&mut self, by: usize)

Source

fn restart_from(&mut self, pos: usize) -> Result<(), Self::Error>

Source

fn error_decoding( &self, byte_range: Range<usize>, reason: Option<&str>, ) -> Self::Error

where E: DecodeErrorHandler<Self>,

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.
