Write Atomic was originally a stripped-down remake of tempfile-fast, but with the 3.4.0 release of tempfile, it has largely been mooted.
(tempfile now supports Linux optimizations like O_TMPFILE natively.)
That said, one might still enjoy the ergonomic single-shot nature of Write Atomic's write_file and copy_file methods, as well as their permission/ownership-syncing behaviors, and so it lives on!
// One line is all it takes:
write_atomic::write_file("/path/to/my-file.txt", b"Some data!").unwrap();Add write_atomic to your dependencies in Cargo.toml, like:
[dependencies]
write_atomic = "0.7.*"
