Trait FromEntitySetIterator

pub trait FromEntitySetIterator<A>: FromIterator<A>
where
    A: EntityEquivalent,
{
    // Required method
    fn from_entity_set_iter<T>(set_iter: T) -> Self
       where T: EntitySet<Item = A>;
}

Conversion from an EntitySetIterator.

Some collections, while they can be constructed from plain iterators, benefit strongly from the additional uniqueness guarantee EntitySetIterator offers. Mirroring Iterator::collect/FromIterator::from_iter, EntitySetIterator::collect_set and FromEntitySetIterator::from_entity_set_iter can be used for construction.

See also: EntitySet.

Required Methods

fn from_entity_set_iter<T>(set_iter: T) -> Self

where T: EntitySet<Item = A>,

Creates a value from an EntitySetIterator.

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.
