Trait SetInterface 

pub trait SetInterface<T: Borrow<Q>, Q: ?Sized>: Sized {
    // Required methods
    fn contains(&self, item: &Q) -> bool;
    fn get(&self, item: &Q) -> Option<&T>;
    fn remove(&mut self, item: &Q) -> Option<T>;
}

Available on crate features collections and traits only.

Required Methods

fn contains(&self, item: &Q) -> bool

Returns true if the set contains item.

fn get(&self, item: &Q) -> Option<&T>

Returns a reference to the contained element equal to the provided item or None if there isn’t one.

fn remove(&mut self, item: &Q) -> Option<T>

Removes item from the set, returning it if it exists.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

impl<T: Hash + Eq + Borrow<Q>, B: BuildHasher, Q: Hash + Eq + ?Sized> SetInterface<T, Q> for HashSet<T, B>
