Enum Instruction

pub enum Instruction {
    Visit(usize),
    Push(ReadOperation),
    Mutate(usize, ReadOperation),
    ExternCall(usize),
}

An enum representing a bytecode instruction. For bytecode mapping, see the byte_id module.

Variants

Visit(usize)

Set the execution pointer index. This is also known as the call or goto instruction.

Push(ReadOperation)

Push data to the stack.

Mutate(usize, ReadOperation)

Mutate a location in the memory pool.

ExternCall(usize)

Call an external function. Similar to the syscall instruction in machine code.

Implementations

impl Instruction

pub fn get_identifier_byte(&self) -> u8

Get the bytecode identifier of this instruction. See the byte_id module for the byte mapping.

pub fn compile(&self, dest: &mut Vec<u8>, program_options: &ProgramOptions)

Compile this instruction to its bytecode representation.
