Advisory cross-platform file locks using file descriptors. Adapted from [mafintosh/fd-lock].
Note that advisory lock compliance is opt-in, and can freely be ignored by other parties. This means this crate should never be used for security purposes, but solely to coordinate file access.
Basic usage ```rust use std::io::prelude::*; use std::fs::File; use fd_lock::RwLock;
// Lock a file and write to it. let mut f = RwLock::new(File::open("foo.txt")?); write!(f.write()?, "chashu cat")?;
// A lock can also be held across multiple operations. let mut f = f.write()?; write!(f, "nori cat")?; write!(f, "bird!")?; ```
sh
$ cargo add fd-lock
This crate uses unsafe on Windows to interface with windows-sys. All
invariants have been carefully checked, and are manually enforced.
