Enum Instruction

pub enum Instruction<'a> {
    PushBytes(&'a PushBytes),
    Op(Opcode),
}

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

Variants

PushBytes(&'a PushBytes)

Push a bunch of data.

Op(Opcode)

Some non-push opcode.

Implementations

impl<'a> Instruction<'a>

pub fn opcode(&self) -> Option<Opcode>

Returns the opcode if the instruction is not a data push.

pub fn push_bytes(&self) -> Option<&PushBytes>

Returns the pushed bytes if the instruction is a data push.

pub fn script_num(&self) -> Option<i64>

Returns the number interpretted by the script parser if it can be coerced into a number.

This does not require the script num to be minimal.

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> Extend<Instruction<'a>> for ScriptBuf

fn extend<T>(&mut self, iter: T)

where T: IntoIterator<Item = Instruction<'a>>,

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

🔬This is a nightly-only experimental API. (extend_one)

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

🔬This is a nightly-only experimental API. (extend_one)

Reserves capacity in a collection for the given number of additional elements.

impl<'a> FromIterator<Instruction<'a>> for ScriptBuf

fn from_iter<T>(iter: T) -> ScriptBuf

where T: IntoIterator<Item = Instruction<'a>>,

Creates a value from an iterator.

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

type Error = TryFromInstructionError

The type returned in the event of a conversion error.

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

Performs the conversion.
