}

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.

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.

Implementations on Foreign Types

impl NestedDecodeInput for &[u8]
