Struct LeasePool 

pub struct LeasePool<T: Default + Reclaim> { /* private fields */ }

Pool of reusable values with single-cell items that are not cloneable.

Items stay in the pool while checked out; Self::acquire hands back a LeaseHandle pointing at one and flags it leased. Dropping the handle reclaims the value and frees the slot, so allocations are reused across acquires instead of allocating anew.

Implementations

impl<T: Default + Reclaim> LeasePool<T>

pub fn with_capacity(capacity: usize) -> Self

Pre-reserve room for capacity pooled items (if exceeded, the pool still grows on demand).

pub fn acquire(&mut self) -> LeaseHandle<T>

Take an item, reusing a free pooled item when available.
