}

This enum represents a single opcode. Under the hood, it’s just a byte. This allows non opcode bytes to be inserted in bytecode streams.

Variants

Con

Load a constant.

NotInit

Load uninitialized Data.

Del

Delete a value off the stack.

FFICall

Calls out to a Rust function via FFI

Copy

Copies topmost value on the stack.

Capture

Moves a variable onto the heap.

Save

Save a constant into a variable.

SaveCap

Save a value to a captured variable.

Load

Push a copy of a variable onto the stack.

LoadCap

Load a copy of a captured variable.

Call

Call a function.

Return

Return from a function.

Closure

Creates a closure over the current local environment.

Print

Prints a value.

Label

Constructs a label.

Tuple

UnData

Destructures atomic data by asserting it matches exactly.

UnLabel

Destructures a label.

UnTuple

Sestructures a tuple.

Implementations

impl Opcode

pub fn from_byte(byte: u8) -> Opcode

Convert a raw byte to an opcode. Note that non-opcode bytes should never be interpreted as an opcode. Under the hood, this is just a transmute, so the regular cautions apply. This should never cause a crash and if it does, the vm’s designed to crash hard so it’ll be pretty obvious.

Trait Implementations

impl Debug for Opcode

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

Formats the value using the given formatter.

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 !=.
