Trait eclectic::set::Base

[src]
pub trait Base: Collection + Iter {
fn is_disjoint(&self, other: &Self) -> bool where Self: Sized;
fn is_subset(&self, other: &Self) -> bool where Self: Sized;
fn insert(&mut self, item: Self::Item) -> bool where Self: AddRemove;
fn replace(&mut self, item: Self::Item) -> Option<Self::Item> where Self: AddRemove;
fn is_superset(&self, other: &Self) -> bool where Self: Sized { ... }
}Set functionality that is independent of an additional type parameter.
It is unusual to use this trait directly. Consider using Set instead.
This trait exists to prevent the ambiguity that would arise if its methods were instead
implemented on Set. In that scenario, set.insert(item) would be ambiguous if the type
of set were S and S: Set<Q> + Set<R>.
Required Methods
fn is_disjoint(&self, other: &Self) -> bool where Self: Sized
Checks if the set is disjoint from the given set.
self is disjoint from other if self contains none of other's items.
fn is_subset(&self, other: &Self) -> bool where Self: Sized
Checks if the set is a subset of the given set.
self is a subset of other if other contains all of self's items.
fn insert(&mut self, item: Self::Item) -> bool where Self: AddRemove
Inserts the given item into the set without replacement.
If the set contains an item that is equivalent to the given item, that item is not replaced with the given item.
Returns true if the given item was inserted into the set, false otherwise.
fn replace(&mut self, item: Self::Item) -> Option<Self::Item> where Self: AddRemove
Inserts the given item into the set with replacement.
If the set contains an item that is equivalent to the given item, that item is replaced with the given item.
Returns the item that was replaced, or None if the set did not contain an equivalent
item.
Provided Methods
fn is_superset(&self, other: &Self) -> bool where Self: Sized
Checks if the set is a superset of the given set.
self is a superset of other if self contains all of other's items.
