Expand description

A Bitcoin Script opcode supported by this engine.

This is a fieldless enum that maps 1:1 to protocol-defined byte values. It derives Copy because it carries no heap data.

Implementations§

impl Opcode

pub fn from_byte(byte: u8) -> Option<Opcode>

Convert a byte to an Opcode, if it maps to a supported opcode.

Returns None for push-data bytes (0x01-0x4e), reserved opcodes, and any unimplemented opcode. These are handled by the tokenizer (push-data) or rejected as unsupported.

pub fn to_byte(self) -> u8

Convert an Opcode back to its canonical byte value.

Trait Implementations§

impl Clone for Opcode

fn clone(&self) -> Opcode

Returns a duplicate of the value. Read more

1.0.0 · Source§

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source. Read more

impl Debug for Opcode

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

Formats the value using the given formatter. Read more

impl Display for Opcode

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

Formats the value using the given formatter. Read more

impl PartialEq for Opcode

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

Tests for self and other values to be equal, and is used by ==.

1.0.0 · Source§

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

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