Implementations

impl OpCode

pub fn from_u8(byte: u8) -> Self

pub fn uses_top(self) -> bool

Check if instruction uses “top” (IT mode - In Top) These instructions depend on the value of ‘top’ from previous instruction For all other instructions, top should be reset to base + nactvar

From Lua 5.5 lopcodes.c:

• CALL: IT=1 (uses top for vararg count)
• TAILCALL: IT=1
• RETURN: IT=1 (uses top for return count)
• SETLIST: IT=1 (uses top for list size)
• VARARGPREP: IT=1 (sets up varargs)

pub fn get_mode(self) -> OpMode

Get the instruction format mode for this opcode Based on Lua 5.5 lopcodes.c luaP_opmodes table

Trait Implementations

impl Clone for OpCode

fn clone(&self) -> OpCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OpCode

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

Formats the value using the given formatter.

impl PartialEq for OpCode

fn eq(&self, other: &OpCode) -> 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 OpCode

impl Eq for OpCode

impl StructuralPartialEq for OpCode
