Trait that allows reading of data into a slice.

Required Methods

fn remaining_len(&mut self) -> usize

The remaining length of the input data.

fn read_into(&mut self, into: &mut [u8]) -> Result<(), DecodeError>

Read the exact number of bytes required to fill the given buffer.

fn read_into_or_exit<ExitCtx: Clone>( &mut self, into: &mut [u8], c: ExitCtx, exit: fn(ExitCtx, DecodeError) -> !, )

Read the exact number of bytes required to fill the given buffer. Exit early if there are not enough bytes to fill the result.

fn read_slice(&mut self, length: usize) -> Result<&[u8], DecodeError>

Read the exact number of bytes required to fill the given buffer.

fn read_slice_or_exit<ExitCtx: Clone>( &mut self, length: usize, c: ExitCtx, exit: fn(ExitCtx, DecodeError) -> !, ) -> &[u8]

Read the exact number of bytes required to fill the given buffer. Exit directly if the input contains too few bytes.

fn flush(&mut self) -> &[u8]

Clears the input buffer and returns all remaining bytes.

Provided Methods

fn empty(&mut self) -> bool

fn read_byte(&mut self) -> Result<u8, DecodeError>

Read a single byte from the input.

fn read_byte_or_exit<ExitCtx: Clone>( &mut self, c: ExitCtx, exit: fn(ExitCtx, DecodeError) -> !, ) -> u8

Read a single byte from the input.

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.
