}

Trait for a set of Variadic Tuples

Required Associated Types

type Schema: PartialEqVariadic

The Schema (aka Variadic type) associated with tuples in this set

Required Methods

fn insert(&mut self, element: Self::Schema) -> bool

Insert an element into the set, return true if successful

fn iter( &self, ) -> impl Iterator<Item = <Self::Schema as VariadicExt>::AsRefVar<'_>>

Iterate over the elements of the set

fn len(&self) -> usize

Return number of elements in the set

fn is_empty(&self) -> bool

Return true if empty

fn drain(&mut self) -> impl Iterator<Item = Self::Schema>

iterate and drain items from the set without deallocating the container

fn contains(&self, value: <Self::Schema as VariadicExt>::AsRefVar<'_>) -> bool

Check for containment

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.
