Crate lockfile[−][src]
This crate provides a lockfile struct that marks a location in the filesystem as locked.
A lock is conceptually created when the file is created, and released when it is deleted.
If the file is already present, the create
function will fail.
Examples
use lockfile::Lockfile; const PATH: &str = "/tmp/some_file/s8329894"; let lockfile = Lockfile::create(PATH)?; assert_eq!(lockfile.path(), Path::new(PATH)); lockfile.release()?; // or just let the lockfile be dropped // File has been unlinked/deleted. assert_eq!(fs::metadata(PATH).unwrap_err().kind(), io::ErrorKind::NotFound);
