This crate provides a simple and cross-platform implementation of named locks. You can use this to lock sections between processes.
use named_lock::NamedLock;
use named_lock::Result;
fn main() -> Result<()> {
let lock = NamedLock::create("foobar")?;
let _guard = lock.lock()?;
// Do something...
Ok(())
}
On UNIX systems this is implemented by using files and flock
. The path of
the created lock file will be /tmp/<name>.lock
.
On Windows this is implemented by creating named mutex with CreateMutexW
.
