Enum bitcoin::util::sighash::Prevouts

pub enum Prevouts<'u, T>where
    T: 'u + Borrow<TxOut>,{
    One(usize, T),
    All(&'u [T]),
}

Contains outputs of previous transactions. In the case SchnorrSighashType variant is SIGHASH_ANYONECANPAY, Prevouts::One may be used.

Variants

One(usize, T)

One variant allows provision of the single prevout needed. It’s useful, for example, when modifier SIGHASH_ANYONECANPAY is provided, only prevout of the current input is needed. The first usize argument is the input index this TxOut is referring to.

All(&'u [T])

When SIGHASH_ANYONECANPAY is not provided, or when the caller is giving all prevouts so the same variable can be used for multiple inputs.

Trait Implementations

impl<'u, T: Clone> Clone for Prevouts<'u, T>where
    T: 'u + Borrow<TxOut>,

fn clone(&self) -> Prevouts<'u, T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'u, T: Debug> Debug for Prevouts<'u, T>where
    T: 'u + Borrow<TxOut>,

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

Formats the value using the given formatter.

impl<'u, T: Hash> Hash for Prevouts<'u, T>where
    T: 'u + Borrow<TxOut>,

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<'u, T: Ord> Ord for Prevouts<'u, T>where
    T: 'u + Borrow<TxOut>,

fn cmp(&self, other: &Prevouts<'u, T>) -> Ordering

This method returns an Ordering between self and other.

const fn max(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the maximum of two values.

const fn min(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the minimum of two values.

const fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl<'u, T: PartialEq> PartialEq<Prevouts<'u, T>> for Prevouts<'u, T>where
    T: 'u + Borrow<TxOut>,

fn eq(&self, other: &Prevouts<'u, T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

const 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<'u, T: PartialOrd> PartialOrd<Prevouts<'u, T>> for Prevouts<'u, T>where
    T: 'u + Borrow<TxOut>,

fn partial_cmp(&self, other: &Prevouts<'u, T>) -> Option<Ordering>

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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