# Fail-safe file sequence

Implemented in Rust.

Inspired by this [Java implementation](https://commons.apache.org/proper/commons-transaction/apidocs/org/apache/commons/transaction/file/FileSequence.html)

## Usage

```rust

let initial_value = 1;

let seq = FileSeq::new(store_dir, initial_value).unwrap();

// Get current value

seq.value().unwrap();

// Increment by 1 and get

seq.increment_and_get(1).unwrap();

// Get, then increment by 1

seq.get_and_increment(1).unwrap();

```
