Struct bitcoin::blockdata::opcodes::All

pub struct All { /* private fields */ }

A script Opcode.

We do not implement Ord on this type because there is no natural ordering on opcodes, but there may appear to be one (e.g. because all the push opcodes appear in a consecutive block) and we don’t want to encourage subtly buggy code. Please use All::classify to distinguish different types of opcodes.

Example of Core bug caused by assuming ordering

Bitcoin Core’s IsPushOnly considers OP_RESERVED to be a “push code”, allowing this opcode in contexts where only pushes are supposed to be allowed.

Implementations

impl All

pub fn classify(self, ctx: ClassifyContext) -> Class

Classifies an Opcode into a broad class.

pub const fn to_u8(self) -> u8

Encodes All as a byte.

Trait Implementations

impl Clone for All

fn clone(&self) -> All

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for All

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

Formats the value using the given formatter.

impl Display for All

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

Formats the value using the given formatter.

impl From<WitnessVersion> for All

fn from(version: WitnessVersion) -> All

Converts WitnessVersion instance into corresponding Bitcoin scriptopcode (OP_0..OP_16).

impl From<u8> for All

fn from(b: u8) -> All

Converts to this type from the input type.

impl PartialEq<All> for All

fn eq(&self, other: &All) -> 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 Serialize for All

Available on crate feature serde only.

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>where S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<All> for WitnessVersion

fn try_from(opcode: All) -> Result<Self, Self::Error>

Converts bitcoin script opcode into WitnessVersion variant.

Returns

Version of the Witness program (for opcodes in range of OP_0..OP_16).

Errors

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

type Error = Error

The type returned in the event of a conversion error.
