FixedInt provides encoding/decoding to and from fixed int representations. The emitted bytestring contains the bytes of the integer in machine endianness.

Required methods

`pub fn required_space() -> usize`[src]

Returns how many bytes are required to represent the given type.

`pub fn encode_fixed(self, src: &mut [u8])`[src]

Encode a value into the given slice. dst must be exactly REQUIRED_SPACE bytes.

`pub fn decode_fixed(src: &[u8]) -> Self`[src]

Decode a value from the given slice. src must be exactly REQUIRED_SPACE bytes.

`pub fn encode_fixed_light<'a>(&'a self) -> &'a [u8]`[src]

Perform a transmute, i.e. return a "view" into the integer's memory, which is faster than performing a copy.

Provided methods

`pub fn encode_fixed_vec(self) -> Vec<u8>`[src]

Helper: Encode the value and return a Vec.

`pub fn decode_fixed_vec(v: &Vec<u8>) -> Self`[src]

Helper: Decode the value from the Vec.
