Crate lendpool

A concurrent pool for lending and reusing items.

This crate provides a LendPool type for managing reusable items in a concurrent or asynchronous context. Items can be checked out (“loaned”) as Loan guards and are automatically returned to the pool when the guard is dropped.

Crate Features

• sync
  Enables the synchronous blocking method [LendPool::loan_sync], which will block the current thread until an item becomes available.

• async
  Enables the asynchronous method [LendPool::loan_async], which will await a notification until an item becomes available.

Examples

use lendpool::LendPool;

// Create a new pool and add items
let pool = LendPool::new();
pool.add(1);
pool.add(2);

// Loan an item (non-blocking)
if let Some(loan) = pool.loan() {
    println!("Got item: {}", *loan);
}; // The `Loan` is dropped here, returning items to the pool
