Migrate 25 crates to monorepo. am: 941f0d157c Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/named-lock/+/3248336 Change-Id: I3f019a0950b0595823bfc57d41ae0e06bf6dd9f9 Signed-off-by: Automerger Merge Worker <[email protected]>
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.
