Methods

impl OpcodePrefix

pub fn from_opcode(op_bytes: &[u8]) -> OpcodePrefix

Extracts the OpcodePrefix from the opcode.

pub fn recipe_name_prefix(self) -> &'static str

Returns the recipe name prefix.

At the moment, each similar OpcodePrefix group is given its own Recipe. In order to distinguish them, this string is prefixed.

Trait Implementations

impl From<u8> for OpcodePrefix

fn from(n: u8) -> OpcodePrefix

Performs the conversion.

impl Clone for OpcodePrefix

fn clone(&self) -> OpcodePrefix

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for OpcodePrefix

impl Eq for OpcodePrefix

impl PartialEq<OpcodePrefix> for OpcodePrefix

fn eq(&self, other: &OpcodePrefix) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn from_primitive(val: u8) -> Option<Self>

Convert from a primitive, might fail.

fn to_primitive(&self) -> u8

Convert to a primitive value.

fn from_str(s: &str) -> Option<Self>
