Build an iAx instruction.

pub fn sj(op: OpCode, j: u32, k: u32) -> Self

Build an isJ instruction.

pub fn is_out_top(self) -> bool

True if this instruction sets L->top for the next instruction.

(testOTMode(GET_OPCODE(i)) && GETARG_C(i) == 0) || GET_OPCODE(i) == OP_TAILCALL

pub fn is_in_top(self) -> bool

True if this instruction uses L->top from the previous instruction.

pub fn op_mode(self) -> Option<OpMode>

Return the OpMode for this instruction.

Trait Implementations

impl Clone for Instruction

fn clone(&self) -> Instruction

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Instruction

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Instruction

fn default() -> Instruction

Returns the “default value” for a type.

impl PartialEq for Instruction

fn eq(&self, other: &Instruction) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Instruction
