fpool

Non-leased object-pooling in Rust.

Non-leased as in: you cannot hold onto objects given from the Pool. This, unfortunately, is not something I could get enforced by the compiler without making the API hard to work with.

Getting started

Add the following to your Cargo.toml file:

toml [dependencies] fpool = "0.3"

Next, add this to your crate:

no_run extern crate fpool;

Examples

A trivial use-case for a round-robin pool:

```rust use fpool::RoundRobinPool;

let mut pool = RoundRobinPool::builder(5, || -> Result<_, ()> { Ok(Vec::new()) }).build().expect("No constructor failure case");

for index in 0..10 { let list = pool.get().expect("No constructor failure case"); list.push(index); }

// The pool now has 5 lists with 2 items each for _ in 0..5 { let list = pool.get().expect("No constructor failure case"); assert_eq!(list.len(), 2); } ```

But a more useful and realistic example is a thread-pool, see examples/thread_pool.rs.
