impl<K, V> FromIterator<(K, V)> for Ctx<K, V>

where K: Ord,

fn from_iter<I: IntoIterator<Item = (K, V)>>(iter: I) -> Self

Creates a value from an iterator.

IntoIterator instance for Ctx

type Item = (K, V)

The type of the elements being iterated over.

type IntoIter = IntoIter<K, V>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<K: Ord, V: Ord> Ord for Ctx<K, V>

fn cmp(&self, other: &Ctx<K, V>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self
