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 nb_nodes(&self) -> usize

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

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

The leaf transactions are unsigned and the node transactions are signed. This is equivalent to unsigned_leaf_txs chained with signed_node_txs

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

Returns all leaf transactions

These transactions aren’t signed (yet)

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

Returns all internal node transactions

These transactions are fully signed

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

Construct the VTXO at the given leaf index.

Panics if leaf_idx is out of range.

pub fn internal_vtxos( &self, ) -> impl Iterator<Item = ServerVtxo<Full>> + ExactSizeIterator + '_

Construct all ServerVtxos

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

Construct all individual vtxos from this round.

pub fn spend_info(&self) -> impl Iterator<Item = (VtxoId, Txid)> + '_
