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 this is implemented by using files and flock
. The path of the
created lock file will be $TMPDIR/<name>.lock
, or /tmp/<name>.lock
if
TMPDIR
environment variable is not set.
On Windows this is implemented by creating named mutex with CreateMutexW
.
