Trait PoolIndex

pub trait PoolIndex<T>: BorrowMut<[usize]> {
    type Item;

    // Required method
    fn extract_item<I: Iterator<Item = T>>(
        &self,
        pool: &LazyBuffer<I>,
    ) -> Self::Item
       where T: Clone;

    // Provided method
    fn len(&self) -> usize { ... }
}

A type holding indices of elements in a pool or buffer of items from an inner iterator and used to pick out different combinations in a generic way.

Required Associated Types

type Item

Required Methods

fn extract_item<I: Iterator<Item = T>>( &self, pool: &LazyBuffer<I>, ) -> Self::Item

where T: Clone,

Provided Methods

fn len(&self) -> usize

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.
