Trait NodeSet

pub trait NodeSet<E>:
    Clone
    + Default
    + Eq {
    // Required methods
    fn len(&self) -> usize;
    fn insert(&mut self, edge: &E) -> bool;
    fn contains(&self, edge: &E) -> bool;
    fn remove(&mut self, edge: &E) -> bool;

    // Provided method
    fn is_empty(&self) -> bool { ... }
}

Set of nodes

Required Methods

fn len(&self) -> usize

Get the number of nodes in the set

fn insert(&mut self, edge: &E) -> bool

Add a node (the node to which edge points) to the set

Returns true if the element was added (i.e. not previously present).

fn contains(&self, edge: &E) -> bool

Return true if the set contains the given node

fn remove(&mut self, edge: &E) -> bool

Remove a node from the set

Returns true if the node was present in the set.

Provided Methods

fn is_empty(&self) -> bool

Returns true iff there are no nodes in the set

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.
