pub fn peek(&self) -> Option<&StackItem<F>>

Returns the top element of the stack, or None if it is empty

pub fn length(&self) -> usize

pub fn deserialize(buf: &[u8]) -> Result<Self, WitnessStackError>

Decompress and deserialize.

Trait Implementations

impl<F: Clone> Clone for WitnessStack<F>

fn clone(&self) -> WitnessStack<F>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<F: Debug> Debug for WitnessStack<F>

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

Formats the value using the given formatter.

impl<F: Default> Default for WitnessStack<F>

fn default() -> WitnessStack<F>

Returns the “default value” for a type.

impl<'de, F> Deserialize<'de> for WitnessStack<F>

where F: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<F> From<WitnessMap<F>> for WitnessStack<F>

fn from(witness: WitnessMap<F>) -> Self

Converts to this type from the input type.

impl<F: Hash> Hash for WitnessStack<F>

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<F: Ord> Ord for WitnessStack<F>

fn cmp(&self, other: &WitnessStack<F>) -> 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<F: PartialEq> PartialEq for WitnessStack<F>

fn eq(&self, other: &WitnessStack<F>) -> 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<F: PartialOrd> PartialOrd for WitnessStack<F>

fn partial_cmp(&self, other: &WitnessStack<F>) -> 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<F> Serialize for WitnessStack<F>

where F: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
