Variants

Clone

clone top of the data_stack and push it

Sp

push current length of data_stack to usize_stack

Pop

Deref

clone where top of the usize_stack points to. Does not pop from usize_stack.

Jump(usize)

jump to label

JumpTrue(usize)

pops data_stack and jump to label if stack_top is true.

JumpFalse(usize)

pops data_stack and jump to label if stack_top is false

GetLocalVariable(usize)

get i’th local variable and push the value to stack_top

SetLocalVariable(usize)

pop data_stack and set i’th local variable to the value. If i’th local variable is Ref, the internal value will be set.

InitLocalVariable(usize)

pop data_stack and initialize i’th local variable to the Value.

IsNil

pop data_stack and check if it is nil.

Nil

push nil

Boolean(bool)

push bool

Numeric(LuaNumber)

push int or float

String(Vec<u8>)

push string

GetEnv

push _ENV

TableInit(usize)

init new table with capacity

TableIndexInit

table -> key -> value -> stack_top. table must not be popped.

TableInitLast(IntType)

sp pushed to usize_stack, points to the start of args. table -> args… -> stack_top ^ sp

TableIndex

table -> index -> stack_top

TableIndexSet

value -> table -> index -> stack_top

FunctionInit(usize, usize)

function_id, number of upvalues

FunctionInitUpvalueFromLocalVar(usize)

func -> top. src_stack_id

FunctionInitUpvalueFromUpvalue(usize)

src_upvalue_id

FunctionUpvalue(usize)

get i’th upvalue of current function

FunctionUpvalueSet(usize)

set i’th upvalue of current function

BinaryAdd

BinarySub

BinaryMul

BinaryDiv

BinaryFloorDiv

BinaryMod

BinaryPow

BinaryConcat

BinaryBitwiseAnd

BinaryBitwiseOr

BinaryBitwiseXor

BinaryShiftLeft

BinaryShiftRight

BinaryEqual

BinaryLessThan

BinaryLessEqual

UnaryMinus

UnaryBitwiseNot

UnaryLength

UnaryLogicalNot

FunctionCall(Option<usize>)

return expected can be 0. sp pushed to usize_stack, points to the start of args. args -> function -> stack top

Return

GetVariadic(Option<usize>)

Invalid call ( using ... in a non-variadic function ) was filtered out in parser.

Trait Implementations

impl Clone for Instruction

fn clone(&self) -> Instruction

Returns a copy 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.
