fpool

Non-leased object-pooling in Rust.

Non-leased as in: objects are not passed out from the Pool, but can be acted upon synchronously. This means that the logic for re-creating and choosing the next item can be done by the pool.

Getting started

Add the following to your Cargo.toml file:

toml [dependencies] fpool = "0.1"

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, || { Ok(Vec::new()) }).build().expect("No constructor failure case");

for index in 0..10 { pool.act_mut(|list| { list.push(index); true // action succeeded and item is still valid }).expect("No constructor failure case"); }

// The pool now has 5 lists with 2 items each for _ in 0..5 { pool.act(|list| { assert_eq!(list.len(), 2); true // action succeeded and item is still valid }).expect("No constructor failure case"); } ```

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