Enum Element

pub enum Element<'txin> {
    Satisfied,
    Dissatisfied,
    Push(&'txin [u8]),
}

Definition of Stack Element of the Stack used for interpretation of Miniscript.

All stack elements with vec![] go to Element::Dissatisfied and vec![1] are marked to Element::Satisfied. Others are directly pushed as witness.

Variants

Satisfied

Result of a satisfied Miniscript fragment Translated from vec![1] from input stack

Dissatisfied

Result of a dissatisfied Miniscript fragment Translated from vec![] from input stack

Push(&'txin [u8])

Input from the witness stack

Implementations

impl<'txin> Element<'txin>

pub fn from_instruction( ins: Result<Instruction<'txin>, Error>, ) -> Result<Self, Error>

Converts a Bitcoin script::Instruction to a stack element

Supports OP_1 but no other numbers since these are not used by Miniscript

Trait Implementations

impl<'txin> Clone for Element<'txin>

fn clone(&self) -> Element<'txin>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'txin> Debug for Element<'txin>

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

Formats the value using the given formatter.

impl<'txin> From<&'txin [u8]> for Element<'txin>

fn from(v: &'txin [u8]) -> Element<'txin>

Converts to this type from the input type.

impl<'txin> From<&'txin Vec<u8>> for Element<'txin>

fn from(v: &'txin Vec<u8>) -> Element<'txin>

Converts to this type from the input type.

impl<'txin> Hash for Element<'txin>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'txin> Ord for Element<'txin>

fn cmp(&self, other: &Element<'txin>) -> 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<'txin> PartialEq for Element<'txin>

fn eq(&self, other: &Element<'txin>) -> 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<'txin> PartialOrd for Element<'txin>

fn partial_cmp(&self, other: &Element<'txin>) -> 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.
