Struct Stack

pub struct Stack<'txin>(/* private fields */);

Stack Data structure representing the stack input to Miniscript. This Stack is created from the combination of ScriptSig and Witness stack.

Implementations

impl<'txin> Stack<'txin>

pub fn is_empty(&self) -> bool

Whether the stack is empty

pub fn len(&self) -> usize

Number of elements on the stack

pub fn pop(&mut self) -> Option<Element<'txin>>

Removes the top stack element, if the stack is nonempty

pub fn push(&mut self, elem: Element<'txin>)

Pushes an element onto the top of the stack

pub fn split_off(&mut self, k: usize) -> Vec<Element<'txin>>

Returns a new stack representing the top k elements of the stack, removing these elements from the original

pub fn last(&self) -> Option<&Element<'txin>>

Returns a reference to the top stack element, if the stack is nonempty

Trait Implementations

impl<'txin> Clone for Stack<'txin>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'txin> Debug for Stack<'txin>

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

Formats the value using the given formatter.

impl<'txin> Default for Stack<'txin>

fn default() -> Stack<'txin>

Returns the “default value” for a type.

impl<'txin> From<Vec<Element<'txin>>> for Stack<'txin>

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

Converts to this type from the input type.

impl<'txin> Hash for Stack<'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> Index<usize> for Stack<'txin>

type Output = Element<'txin>

The returned type after indexing.

fn index(&self, index: usize) -> &Self::Output

Performs the indexing (container[index]) operation.

impl<'txin> Ord for Stack<'txin>

fn cmp(&self, other: &Stack<'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 Stack<'txin>

fn eq(&self, other: &Stack<'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 Stack<'txin>

fn partial_cmp(&self, other: &Stack<'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.
