Full set of instructions

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ControlFlow(ControlFlowOp)

Control-flow instructions

Put(PutOp)

Instructions setting register values

Move(MoveOp)

Instructions moving and swapping register values

Cmp(CmpOp)

Instructions comparing register values

Arithmetic(ArithmeticOp)

Arithmetic instructions

Bitwise(BitwiseOp)

Bit operations & boolean algebra instructions

Bytes(BytesOp)

Operations on byte strings

Digest(DigestOp)

Cryptographic hashing functions

ExtensionCodes(Extension)

Extension operations which can be provided by a host environment

Nop

No-operation instruction

Trait Implementations

impl<Extension> Bytecode for Instr<Extension> where
    Extension: InstructionSet, 

fn byte_count(&self) -> u16

Returns number of bytes which instruction and its argument occupies

fn instr_range() -> RangeInclusive<u8>

Returns range of instruction btecodes covered by a set of operations

fn instr_byte(&self) -> u8

Returns byte representing instruction code (without its arguments)

fn write_args<W>(&self, writer: &mut W) -> Result<(), EncodeError> where
    W: Write,
    EncodeError: From<<W as Write>::Error>, 

Writes instruction arguments as bytecode, omitting instruction code byte

fn read<R>(reader: &mut R) -> Result<Self, DecodeError> where
    R: Read,
    DecodeError: From<<R as Read>::Error>, 

Reads the instruction from bytecode

fn write<W>(&self, writer: &mut W) -> Result<(), EncodeError> where
    W: Write,

impl<Extension: Debug> Debug for Instr<Extension> where
    Extension: InstructionSet, 

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

Formats the value using the given formatter.

impl<Extension> Display for Instr<Extension> where
    Extension: InstructionSet, 

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