The operation code.

Variants

Pop

Removes the top-of-stack (TOS) item.

Dup

Duplicates the reference on top of the stack.

DupTwo

Duplicates the two references on top of the stack, leaving them in the same order.

RotTwo

Swaps the two top-most stack items.

RotThree

Lifts second and third stack item one position up, moves top down to position three.

LoadLocal(usize)

Pushes the value associated with local_names[namei] onto the stack.

LoadGlobal(usize)

Pushes the value associated with global_names[namei] onto the stack.

LoadUpvalue(usize)

Pushes the value associated with upvalue_names[namei] onto the stack.

LoadConst(usize)

Pushes consts[consti] onto the stack.

StoreLocal(usize)

Stores TOS into the local_names[namei].

StoreGlobal(usize)

Stores TOS into the global_names[namei].

StoreUpvalue(usize)

Stores TOS into the upvalue_names[namei].

Import(usize)

Imports the module consts[consti] and pushed it onto the stack.

ImportFrom(usize)

Loads the attribute consts[consti] the module found in TOS and pushed it onto the stack.

ImportGlob

LoLoads all symbols from the module TOS to the global namespace.

BuildTable(usize)

Pushes a new table onto the stack. Pops 2 * count items to build table.

BuildList(usize)

Pushes a new list onto the stack. Pops count items to build list.

GetAttr

Implements TOS = TOS1::TOS.

GetItem

Implements TOS = TOS1[TOS].

GetMeta

Implements TOS = TOS[#].

SetAttr

Implements TOS1::TOS = TOS2.

SetItem

Implements TOS1[TOS] = TOS2.

SetMeta

Implements TOS[#] = TOS1.

Neg

Implements TOS = -TOS.

Not

Implements TOS = not TOS.

Add

Implements TOS = TOS1 + TOS.

Sub

Implements TOS = TOS1 - TOS.

Mul

Implements TOS = TOS1 * TOS.

Div

Implements TOS = TOS1 / TOS.

Mod

Implements TOS = TOS1 % TOS.

Eq

Implements TOS = TOS1 == TOS.

Ne

Implements TOS = TOS1 != TOS.

Gt

Implements TOS = TOS1 > TOS.

Ge

Implements TOS = TOS1 >= TOS.

Lt

Implements TOS = TOS1 < TOS.

Le

Implements TOS = TOS1 <= TOS.

Is

Implements TOS = TOS1 is TOS.

For(JumpTarget)

If TOS is iterable or callable, call TOS and get the return value, if the return value if null, jump to target, else push the return value onto the stack. Used in for statement.

Jump(JumpTarget)

Sets the bytecode counter to target.

JumpIfNull(JumpTarget)

If TOS is null, sets the bytecode counter to target.

JumpPopIfFalse(JumpTarget)

If TOS is false, sets the bytecode counter to target. TOS is popped.

JumpIfTureOrPop(JumpTarget)

If TOS is true, sets the bytecode counter to target and leaves TOS on the stack. Otherwise, TOS is popped.

JumpIfFalseOrPop(JumpTarget)

If TOS is false, sets the bytecode counter to target and leaves TOS on the stack. Otherwise, TOS is popped.

Call(usize)

Pops numbers of item for function arguments, then pop an callable value and call it.

TryCall(usize)

Call with a shortcut for propagating errors.

Return

Returns with TOS to the caller of the function.

Throw

Returns with TOS as a error.

ReturnCall(usize)

Same as “Call(usize); Return;”, this is for tail call optimization.

JumpTarget(JumpTarget)

A jump target, only used during code generation.

Trait Implementations

impl Clone for OpCode

fn clone(&self) -> OpCode

Returns a copy 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 Display for OpCode

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

Formats the value using the given formatter.

impl Ord for OpCode

fn cmp(&self, other: &OpCode) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<OpCode> for OpCode

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

This method tests for self and other values to be equal, and is used by ==.

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

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

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<BinOp> for OpCode

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: BinOp) -> Result<Self>

Performs the conversion.

impl Eq for OpCode
