Enum Entry

pub enum Entry<'a, T, V, Ix: IndexType = DefaultIx> {
    Vacant(VacantEntry<'a, T, V, Ix>),
    Occupied(OccupiedEntry<'a, T, V, Ix>),
}

A view into a single entry in an IntervalMap, which may either be vacant or occupied. This enum is constructed from the entry.

Variants

Vacant(VacantEntry<'a, T, V, Ix>)

Occupied(OccupiedEntry<'a, T, V, Ix>)

Implementations

impl<'a, T, V, Ix: IndexType> Entry<'a, T, V, Ix>

where T: Copy,

pub fn interval(&self) -> Range<T>

Returns the interval that was used for the search.

impl<'a, T, V, Ix: IndexType> Entry<'a, T, V, Ix>

where T: Copy + PartialOrd,

pub fn or_insert(self, default: V) -> &'a mut V

If value is missing, initializes it with the default value. In any case, returns a mutable reference to the value.

pub fn or_insert_with<F>(self, default: F) -> &'a mut V

where F: FnOnce() -> V,

If value is missing, initializes it with a default() function call. In any case, returns a mutable reference to the value.

pub fn or_insert_with_interval<F>(self, default: F) -> &'a mut V

where F: FnOnce(Range<T>) -> V,

If value is missing, initializes it with a default(interval). In any case, returns a mutable reference to the value.

pub fn and_modify<F>(self, f: F) -> Self

where F: FnOnce(&mut V),

If the entry is occupied, modifies the value with f function, and returns a new entry. Does nothing if the value was vacant.

impl<'a, T, V, Ix: IndexType> Entry<'a, T, V, Ix>

where T: Copy + PartialOrd, V: Default,

pub fn or_default(self) -> &'a mut V

If value is missing, initializes it with V::default(). In any case, returns a mutable reference to the value.

Trait Implementations

impl<'a, T, V, Ix: IndexType> Debug for Entry<'a, T, V, Ix>

where T: PartialOrd + Copy + Debug, V: Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
