A buffered reader of some kind.

The lifetime 'de allows the output of deserialization to borrow from the input.

Required Methods

fn get_chunk(&mut self, size: usize) -> Option<&'de [u8]>

Reads and returns a chunk of .len() = size advancing the cursor iff self.remaining() >= size.

fn remaining(&self) -> usize

Returns the number of bytes left to read in the input.

Provided Methods

fn get_array_chunk<const N: usize>(&mut self) -> Option<&'de [u8; N]>

Reads and returns a chunk of .len() = N as an array, advancing the cursor.

fn get_slice(&mut self, size: usize) -> Result<&'de [u8], DecodeError>

Reads and returns a byte slice of .len() = size advancing the cursor.

fn get_array<const N: usize>(&mut self) -> Result<&'de [u8; N], DecodeError>

Reads an array of type [u8; N] from the input.

fn get_u8(&mut self) -> Result<u8, DecodeError>

Reads a u8 in little endian (LE) encoding from the input.

This method is provided for convenience and is derived from get_chunk’s definition.

fn get_u16(&mut self) -> Result<u16, DecodeError>

Reads a u16 in little endian (LE) encoding from the input.

This method is provided for convenience and is derived from get_chunk’s definition.

fn get_u32(&mut self) -> Result<u32, DecodeError>

Reads a u32 in little endian (LE) encoding from the input.

This method is provided for convenience and is derived from get_chunk’s definition.

fn get_u64(&mut self) -> Result<u64, DecodeError>

Reads a u64 in little endian (LE) encoding from the input.

This method is provided for convenience and is derived from get_chunk’s definition.

fn get_u128(&mut self) -> Result<u128, DecodeError>

Reads a u128 in little endian (LE) encoding from the input.

This method is provided for convenience and is derived from get_chunk’s definition.

fn get_u256(&mut self) -> Result<U256, DecodeError>

Reads a u256 in little endian (LE) encoding from the input.

This method is provided for convenience and is derived from get_chunk’s definition.

fn get_i8(&mut self) -> Result<i8, DecodeError>

Reads an i8 in little endian (LE) encoding from the input.

This method is provided for convenience and is derived from get_chunk’s definition.

fn get_i16(&mut self) -> Result<i16, DecodeError>

Reads an i16 in little endian (LE) encoding from the input.

This method is provided for convenience and is derived from get_chunk’s definition.

fn get_i32(&mut self) -> Result<i32, DecodeError>

Reads an i32 in little endian (LE) encoding from the input.

This method is provided for convenience and is derived from get_chunk’s definition.

fn get_i64(&mut self) -> Result<i64, DecodeError>

Reads an i64 in little endian (LE) encoding from the input.

This method is provided for convenience and is derived from get_chunk’s definition.

fn get_i128(&mut self) -> Result<i128, DecodeError>

Reads an i128 in little endian (LE) encoding from the input.

This method is provided for convenience and is derived from get_chunk’s definition.

fn get_i256(&mut self) -> Result<I256, DecodeError>

Reads an i256 in little endian (LE) encoding from the input.

This method is provided for convenience and is derived from get_chunk’s definition.

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.
