Crossbeam-STM

Crossbeam-STM is a Software Transactional Memory implementation using crossbeam-epoch for memory reclamation. It is meant to be as fast and consistent as possible for load speed, at the expense of having inconsistent-timed and potentially very slow writes.

*THIS PROJECT IS NOT READY FOR GENERAL USAGE.*

Example

```rust extern crate crossbeam_stm;

use crossbeam_stm::Stm;

// Create a new STM pointer with a Vec of numbers let stm = Stm::new(Some(vec![1,2,3,4]);

// Read from the STM { let guard = stm.guard() let data = guard.load() println!("Current STM: {:?}", data); }

// Update the STM pointer to add a new number stm.update(|value| { // Since value is an Option, map over it value.map(|data| { let mut data = data.clone(); data.push(5); data } });

// Read the new data { let guard = stm.guard() let data = guard.load() println!("Current STM: {:?}", data); }

```
