Struct ProgramCounter

struct ProgramCounter {
    range: Range<*const u8>,
    pc: *const u8,
}

An program counter. This is implemented as a bound checked range pointer.

Fields

range: Range<*const u8>

Valid range for this instruction pointer.

pc: *const u8

Points to the next instruction.

fn as_offset(&self) -> usize

fn goto(&mut self, offset: u16)

fn next(&mut self) -> u8

Take the next byte in the stream

fn arg1(&mut self) -> u16
