There is no better name for this project
A Distributed Locking System (DLS) made for CockroachDB and Postgres written in pure Rust. Motivation for this project was to create a DLS that didn't use the Redis Redlock protocol (since I saw some nerds arguing about it on the internet). This project also contains more features than traditional Redlock implementations.

```rs use std::thread::sleep; use std::time::Duration;
use cocklock::{errors::CockLockError::NotAvailable, CockLock};
fn my_task() { println!("Doing my task."); }
fn main() { let mut locker = CockLock::builder() .withconnectionstrings(vec!["postgres://user:pass@localhost:5432/db"]) .build() .unwrap();
loop {
match locker.lock("task", 10_000) {
Ok(_) => my_task(),
Err(err) => match err {
NotAvailable => println!("Someone else is doing my task!"),
_ => println!("Uh oh, some other error occurred: {err}")
},
};
sleep(Duration::from_millis(1_000));
}
} ```
