pub struct DefaultRecycle(_);
Expand description

A Recycle implementation for any type implementing Default and Clone.

This creates new elements by calling using Default::default(). Existing elements are recycled by calling Clone::clone_from with the default value.

Allocation Reuse

Clone::clone_from is not guaranteed to reuse existing allocations in place. For a number of common types in the standard library, such as Box, String, Vec, and collections based on Vec (such as VecDeque and BinaryHeap), clone_from is overridden to reuse existing allocations in place. However, other types may not override clone_from in this way.

DefaultRecycle will always work for types that implement Default and Clone, but it cannot be guaranteed to always reuse allocations. For a more restrictive Recycle implementation that will always reuse existing allocations, consider WithCapacity.
