Enum 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 TapSighashType 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 for Prevouts<'u, T>

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

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'u, T> Debug for Prevouts<'u, T>

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

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

Formats the value using the given formatter.

impl<'u, T> Hash for Prevouts<'u, T>

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

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

where __H: Hasher,

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 for Prevouts<'u, T>

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

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

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

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

where T: PartialOrd + '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.

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<'u, T> Eq for Prevouts<'u, T>

where T: Eq + 'u + Borrow<TxOut>,

impl<'u, T> StructuralPartialEq for Prevouts<'u, T>

where T: 'u + Borrow<TxOut>,
