}

Trait that allows deserializing objects from a buffer.

Required Methods

fn remaining_len(&self) -> usize

The remaining length of the input data.

fn peek_into<H>(&mut self, into: &mut [u8], h: H) -> Result<(), H::HandledErr>

where H: DecodeErrorHandler,

Read the exact number of bytes required to fill the given buffer, without consuming the underlying bytes.

Will fail is not enough bytes left in buffer.

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

where H: DecodeErrorHandler,

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

Will fail is not enough bytes left in buffer.

Provided Methods

fn is_depleted(&self) -> bool

True if all data from the buffer has already been used.

fn supports_specialized_type<T: TryStaticCast>() -> bool

fn read_specialized<T, C, H>( &mut self, _context: C, h: H ) -> Result<T, H::HandledErr>

where T: TryStaticCast, C: TryStaticCast, H: DecodeErrorHandler,

fn read_byte<H>(&mut self, h: H) -> Result<u8, H::HandledErr>

where H: DecodeErrorHandler,

Read a single byte from the input.

Object Safety

This trait is not object safe.
