Commit log library for rust. It is intended to be used in various higher-level distributed abstractions on top of a distributed log.
First, add this to your Cargo.toml:
toml
[dependencies]
commitlog = "0.0.1"
```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("hello world").unwrap(); // offset 0
log.append("second message").unwrap(); // offset 1
// read the messages
let messages = log.read(ReadPosition::Beginning, ReadLimit::Messages(2)).unwrap();
for msg in messages.iter() {
println!("{} - {}", msg.offset(), String::from_utf8_lossy(msg.payload()));
}
// prints:
// 0 - hello world
// 1 - second message
}
```
