Expand description

Trait for Interpreter to be able to jump

Required Methods§

fn relative_jump(&mut self, offset: isize)

Relative jumps does not require checking for overflow.

fn absolute_jump(&mut self, offset: usize)

Absolute jumps require checking for overflow and if target is a jump destination from jump table.

fn is_valid_legacy_jump(&mut self, offset: usize) -> bool

Check legacy jump destination from jump table.

fn pc(&self) -> usize

Returns current program counter.

fn opcode(&self) -> u8

Returns instruction opcode.
