Variants

HALT

Stop all execution instantly.

LOAD

MOVE

Move a value from a register to a memory location or vice versa. The first argument is the source, the second is the destination. Swap the arguments to change the direction. The source will be cleared after the operation.

This opcode is followed by two 64-bit unsigned integers.

COPY

Copy a value from a register to a memory location or vice versa. The source will be left untouched.

This opcode is followed by two 64-bit unsigned integers.

CALCULATE

Perform a calculation (ADD, SUBTRACT, MULTIPLY, DIVIDE) on two registers and write the result to a third.

This opcode is followed by three 16-bit unsigned integers.

COMPARE

Perform a comparison (EQ, NEQ, LT, LTE, GT, GTE) on two registers and write the result to a third.

This opcode is followed by three 16-bit unsigned integers.

BITWISE

Perform a bitwise operation (AND, OR, XOR, NOT, LSH, RSH) on two or three addresses.

JUMP

Set the program counter to a value from a location, using one of the methods (absolute, forward, backward)

JUMPC

Set the program counter to a value from a location if the byte at a given address in memory has the value of 1

INTERRUPT

Emit an event that needs immediate attention (READ, PRINT)

CALL

RETURN

PUSH

APPEND

ILLEGAL

An invalid opcode.

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 From<u8> for Opcode

fn from(byte: u8) -> Opcode

Converts to this type from the input type.

impl Hash for Opcode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Into<Opcode> for Instruction

fn into(self) -> Opcode

Converts this type into the (usually inferred) input type.

impl Into<u8> for Opcode

fn into(self) -> u8

Converts this type into the (usually inferred) input type.

impl PartialEq 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.

impl Eq for Opcode

impl StructuralEq for Opcode

impl StructuralPartialEq for Opcode
