Struct CachedSignedVtxoTree

pub struct CachedSignedVtxoTree {
    pub spec: SignedVtxoTreeSpec,
    pub txs: Vec<Transaction>,
}

A fully signed VTXO tree, with all the transaction cached.

This is useful for cheap extraction of VTXO branches.

Fields

spec: SignedVtxoTreeSpec

txs: Vec<Transaction>

All signed txs in this tree, starting with the leaves, towards the root.

Implementations

impl CachedSignedVtxoTree

pub fn exit_branch(&self, leaf_idx: usize) -> Vec<&Transaction>

Construct the exit branch starting from the root ending in the leaf.

Panics if leaf_idx is out of range.

pub fn nb_leaves(&self) -> usize

pub fn all_final_txs(&self) -> &[Transaction]

Get all final txs in this tree, starting with the leaves, towards the root.

pub fn build_vtxo(&self, leaf_idx: usize) -> Vtxo

Construct the VTXO at the given leaf index.

Panics if leaf_idx is out of range.

pub fn all_vtxos(&self) -> impl Iterator<Item = Vtxo> + ExactSizeIterator + '_

Construct all individual vtxos from this round.
