Trait protocoll::Set
[−]
[src]
pub trait Set<T> where Self: Sized { fn fun<'a, Q: ?Sized>(&'a self) -> Box<Fn(&Q) -> Option<&'a T> + 'a> where T: Borrow<Q>, Q: Hash + Ord; fn inc(self, i: T) -> Self; fn dec<Q: ?Sized>(self, i: &Q) -> Self where T: Borrow<Q>, Q: Hash + Ord; fn shrink(self) -> Self; fn empty(self) -> Self; fn absorb<I>(self, coll: I) -> Self where I: IntoIterator<Item=T> { ... } }
basic protocol for sets.
Required Methods
fn fun<'a, Q: ?Sized>(&'a self) -> Box<Fn(&Q) -> Option<&'a T> + 'a> where T: Borrow<Q>, Q: Hash + Ord
a set maps from items to themselves.
fn inc(self, i: T) -> Self
adds item i.
fn dec<Q: ?Sized>(self, i: &Q) -> Self where T: Borrow<Q>, Q: Hash + Ord
removes item i.
fn shrink(self) -> Self
shrink_to_fit.
fn empty(self) -> Self
clear.
Provided Methods
fn absorb<I>(self, coll: I) -> Self where I: IntoIterator<Item=T>
takes another collection into this one.
