Struct TieredMulti

pub struct TieredMulti<T>(Tiered<Vec<T>>);

Represents notes of different denominations.

Attention: care has to be taken when constructing this to avoid overflow when calculating the total amount represented. As it is prudent to limit both the maximum note amount and maximum note count per transaction this shouldn’t be a problem in practice though.

Implementations

impl<T> TieredMulti<T>

pub fn new(map: BTreeMap<Amount, Vec<T>>) -> Self

Returns a new TieredMulti with the given BTreeMap map

pub fn new_aggregate_from_tiered_iter( tiered_iter: impl Iterator<Item = Tiered<T>>, ) -> Self

Returns a new TieredMulti from a collection of Tiered structs. The Tiered structs are expected to be structurally equal, otherwise this function will panic.

pub fn total_amount(&self) -> Amount

Returns the total value of all notes in msat as Amount

pub fn count_items(&self) -> usize

Returns the number of items in all vectors

pub fn count_tiers(&self) -> usize

Returns the number of tiers

pub fn summary(&self) -> TieredCounts

Returns the summary of number of items in each tier

pub fn is_empty(&self) -> bool

Verifies whether all vectors in all tiers are empty

pub fn iter(&self) -> impl Iterator<Item = (Amount, &Vec<T>)>

Returns an borrowing iterator

pub fn iter_items(&self) -> impl DoubleEndedIterator<Item = (Amount, &T)>

Returns an iterator over every (Amount, &T)

Note: The order of the elements is important: from the lowest tier to the highest, then in order of elements in the Vec

pub fn into_iter_items(self) -> impl DoubleEndedIterator<Item = (Amount, T)>

Returns an consuming iterator over every (Amount, T)

Note: The order of the elements is important: from the lowest tier to the highest, then in order of elements in the Vec

pub fn push(&mut self, amt: Amount, val: T)

fn assert_invariants(&self)
