Expand description
FixedInt
provides encoding/decoding to and from fixed int representations.
The emitted bytestring contains the bytes of the integer in machine endianness.
Required Associated Constants
const REQUIRED_SPACE: usize
Required Methods
fn required_space() -> usize
fn required_space() -> usize
Returns how many bytes are required to represent the given type.
fn encode_fixed(self, dst: &mut [u8])
fn encode_fixed(self, dst: &mut [u8])
Encode a value into the given slice. dst
must be exactly REQUIRED_SPACE
bytes.
fn decode_fixed(src: &[u8]) -> Self
fn decode_fixed(src: &[u8]) -> Self
Decode a value from the given slice. src
must be exactly REQUIRED_SPACE
bytes.
Provided Methods
fn encode_fixed_vec(self) -> Vec<u8>
fn encode_fixed_vec(self) -> Vec<u8>
Helper: Encode the value and return a Vec.
fn decode_fixed_vec(v: &Vec<u8>) -> Self
fn decode_fixed_vec(v: &Vec<u8>) -> Self
Helper: Decode the value from the Vec.
