Enum Witness

pub enum Witness {
    Stack(Vec<Vec<u8>>),
    Unavailable,
    Impossible,
}

A witness, if available, for a Miniscript fragment

Variants

Stack(Vec<Vec<u8>>)

Witness Available and the value of the witness

Unavailable

Third party can possibly satisfy the fragment but we cannot Witness Unavailable

Impossible

No third party can produce a satisfaction without private key Witness Impossible

Implementations

impl Witness

pub fn ripemd160_preimage<Pk: ToPublicKey, S: Satisfier<Pk>>( sat: S, h: &Pk::Ripemd160, ) -> Self

impl Witness

pub fn hash_dissatisfaction() -> Self

Produce something like a 32-byte 0 push

pub fn empty() -> Self

Construct a satisfaction equivalent to an empty stack

pub fn push_1() -> Self

Trait Implementations

impl Clone for Witness

fn clone(&self) -> Witness

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Witness

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

Formats the value using the given formatter.

impl Ord for Witness

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Witness

fn eq(&self, other: &Witness) -> 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 PartialOrd for Witness

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Eq for Witness
