Trait Implementations

impl<T: Clone> NodeInfo for SpansInfo<T>

type L = SpansLeaf<T>

The type of the leaf.

fn accumulate(&mut self, other: &Self)

An operator that combines info from two subtrees. It is intended (but not strictly enforced) that this operator be associative and obey an identity property. In mathematical terms, the accumulate method is the operation of a monoid.

fn compute_info(l: &SpansLeaf<T>) -> Self

A mapping from a leaf into the info type. It is intended (but not strictly enforced) that applying the accumulate method to the info derived from two leaves gives the same result as deriving the info from the concatenation of the two leaves. In mathematical terms, the compute_info method is a monoid homomorphism.

fn identity() -> Self

The identity of the monoid. Need not be implemented because it can be computed from the leaf default.

fn interval(&self, len: usize) -> Interval

The interval covered by the first len base units of this node. The default impl is sufficient for most types, but interval trees may need to override it.

impl<T: Clone> Clone for SpansInfo<T>

fn clone(&self) -> SpansInfo<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
