Enum Instruction

pub enum Instruction<'a> {
    PushBytes(&'a [u8]),
    Op(All),
}

A “parsed opcode” which allows iterating over a Script in a more sensible way.

Variants

PushBytes(&'a [u8])

Push a bunch of data.

Op(All)

Some non-push opcode.

Trait Implementations

impl<'a> Clone for Instruction<'a>

fn clone(&self) -> Instruction<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Instruction<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for Instruction<'a>

fn eq(&self, other: &Instruction<'a>) -> bool

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

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

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

impl<'a> TryFrom<Instruction<'a>> for WitnessVersion

fn try_from( instruction: Instruction<'_>, ) -> Result<WitnessVersion, <WitnessVersion as TryFrom<Instruction<'a>>>::Error>

Converts bitcoin script Instruction (parsed opcode) into WitnessVersion variant.

Returns

Version of the Witness program for Instruction::Op and Instruction::PushBytes with byte value within 1..=16 range.

Errors

If the opcode does not correspond to any witness version, errors with Error::MalformedWitnessVersion for the rest of opcodes.

type Error = Error

The type returned in the event of a conversion error.
