Trait SetLike 

pub trait SetLike {
    type Item: Hash + Eq + Display + Clone;

    // Required methods
    fn contains(&self, item: &Self::Item) -> bool;
    fn is_empty(&self) -> bool;
}

Represents a generic set-like container with members.

Required Associated Types

type Item: Hash + Eq + Display + Clone

The type of items stored in the set.

Required Methods

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

Returns true if the set contains the specified item.

fn is_empty(&self) -> bool

Returns true if the set is empty.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
