Struct bdk_chain::tx_graph::ChangeSet

source ·
pub struct ChangeSet<A = ()> {
    pub txs: BTreeSet<Arc<Transaction>>,
    pub txouts: BTreeMap<OutPoint, TxOut>,
    pub anchors: BTreeSet<(A, Txid)>,
    pub last_seen: BTreeMap<Txid, u64>,
}
Expand description

The ChangeSet represents changes to a TxGraph.

Since TxGraph is monotone, the “changeset” can only contain transactions to be added and not removed.

Refer to module-level documentation for more.

Fields§

§txs: BTreeSet<Arc<Transaction>>

Added transactions.

§txouts: BTreeMap<OutPoint, TxOut>

Added txouts.

§anchors: BTreeSet<(A, Txid)>

Added anchors.

§last_seen: BTreeMap<Txid, u64>

Added last-seen unix timestamps of transactions.

Implementations§

source§

impl<A> ChangeSet<A>

source

pub fn txouts(&self) -> impl Iterator<Item = (OutPoint, &TxOut)>

Iterates over all outpoints contained within ChangeSet.

source

pub fn anchor_heights(&self) -> impl Iterator<Item = u32> + '_
where A: Anchor,

Iterates over the heights of that the new transaction anchors in this changeset.

This is useful if you want to find which heights you need to fetch data about in order to confirm or exclude these anchors.

source§

impl<A: Ord> ChangeSet<A>

source

pub fn map_anchors<A2: Ord, F>(self, f: F) -> ChangeSet<A2>
where F: FnMut(A) -> A2,

Transform the ChangeSet to have Anchors of another type.

This takes in a closure of signature FnMut(A) -> A2 which is called for each Anchor to transform it.
