Struct Instruction 

pub struct Instruction {
    pub op: Opcode,
    pub a: u8,
    pub b: u8,
    pub c: u8,
    pub imm: i32,
}

A single packed instruction word.

Layout is 8 bytes (op + a/b/c + signed imm) so a Vec<Instruction> stays dense and the interpreter can fetch with a single aligned load. Operand meaning is opcode-specific; see Opcode and [crate::builder].

Fields

op: Opcode

a: u8

b: u8

c: u8

imm: i32

Implementations

impl Instruction

pub fn new(op: Opcode, a: u8, b: u8, c: u8, imm: i32) -> Self

pub fn nullary(op: Opcode) -> Self

pub fn abc(op: Opcode, a: u8, b: u8, c: u8) -> Self

pub fn a_imm(op: Opcode, a: u8, imm: i32) -> Self

pub fn only_imm(op: Opcode, imm: i32) -> Self
