Trait Implementations

impl<Id, T> Cardinality<Id, T> for ExactlyOne<Id, T>

type Rebind<U> = ExactlyOne<Id, U>

Same cardinality with a different inner type.

fn map<N>(&self, map: impl FnMut(&Id, &T) -> N) -> Self::Rebind<N>

where Id: Clone,

Maps values by reference while preserving cardinality.

fn map_mut<N>(self, map: impl FnMut(T) -> N) -> Self::Rebind<N>

Maps values by value while preserving cardinality.

fn get(&self, id: &Id) -> Option<&T>

where Id: Hash + Eq,

Returns the value associated with id, if present.

impl<Id: Clone, T: Clone> Clone for ExactlyOne<Id, T>

fn clone(&self) -> ExactlyOne<Id, T>
