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

Required Methods

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

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

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

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

Provided Methods

Helper: Encode the value and return a Vec.

Helper: Decode the value from the Vec.
