Trait HasMember

pub trait HasMember<A> {
    // Required method
    fn has_member(&self, element: &A) -> bool;
}

Determines whether the given element is part of a value or member of a collection.

This is usually a property of some kind of container like String, Vec, HashSet or &[T].

Required Methods

fn has_member(&self, element: &A) -> bool

Returns whether the given element is part of this value or a member of it
