Commit log library for rust. It is intended to be used in various higher-level distributed abstractions on top of a distributed log.
```rust extern crate commitlog;
use commitlog::*;
fn main() { // open a directory called 'log' for segment and index storage let opts = LogOptions::new("log"); let mut log = CommitLog::new(opts).unwrap();
// append to the log
log.append(b"hello world").unwrap(); // offset 0
log.append(b"second message").unwrap(); // offset 1
// read the messages
let messages = log.read(ReadPosition::Beginning, ReadLimit::Messages(2)).unwrap();
for msg in messages {
println!("{} - {}", msg.offset(), String::from_utf8_lossy(msg.payload()));
}
// prints:
// 0 - hello world
// 1 - second message
}
```
