Implementations

impl OpcodePrefix

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

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.
