Decode a u8.

fn decode_u16(&mut self) -> Result<u16, DecodeError>

Decode a u16.

fn decode_u32(&mut self) -> Result<u32, DecodeError>

Decode a u32.

fn decode_u64(&mut self) -> Result<u64, DecodeError>

Decode a u64.

fn decode_u128(&mut self) -> Result<u128, DecodeError>

Decode a i8.

fn decode_i16(&mut self) -> Result<i16, DecodeError>

Decode a i16.

fn decode_i32(&mut self) -> Result<i32, DecodeError>

Decode a i32.

fn decode_i64(&mut self) -> Result<i64, DecodeError>

Decode a i64.

fn decode_i128(&mut self) -> Result<i128, DecodeError>

Decode a i128.

fn decode_borrowed_str(&mut self) -> Result<&'a str, DecodeError>

Decode a borrowed str.

fn decode_owned_str(&mut self) -> Result<String, DecodeError>

Decode an owned String.

fn decode_borrowed_bytes(&mut self) -> Result<&'a [u8], DecodeError>

Decode borrowed bytes.

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