Implementations§

impl Operator

fn read(cursor: &mut Cursor<'_>, b0: u8) -> Option<Self>

fn from_opcode(opcode: u8) -> Option<Self>

Creates an operator from the given opcode.

pub fn from_two_byte_opcode(opcode: u8) -> Option<Self>

Creates an operator from the given extended opcode.

These are preceded by a byte containing the escape value of 12.
