Enum sapio_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 ANYONECANPAY, Prevouts::One may be provided

Variants

One(usize, T)

One variant allows to provide the single Prevout needed. It’s useful for example when modifier 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 ANYONECANPAY is not provided, or the caller is handy giving all prevouts so the same variable can be used for multiple inputs.
