Struct fedimint_core::tiered_multi::TieredMulti

pub struct TieredMulti<T>(/* private fields */);

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 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 iter_tiers(&self) -> impl Iterator<Item = &Amount>

Returns an iterator over the keys

pub fn summary(&self) -> TieredSummary

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 structural_eq<O>(&self, other: &TieredMulti<O>) -> bool

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

Returns an borrowing iterator

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

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

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 longest_tier_except(&self, except: &Amount) -> usize

Returns the length of the longest vector of all tiers, ignoring the except tier

pub fn all_tiers_exist_in<K>( &self, keys: &Tiered<K> ) -> Result<(), InvalidAmountTierError>

Verifies that all keys in self are present in the keys of the given parameter Tiered

pub fn get(&self, amt: Amount) -> Option<&Vec<T>>

Returns an Option with a reference to the vector of the given Amount

pub fn get_mut(&mut self, amt: Amount) -> Option<&mut Vec<T>>
