openat crate is a low-level API, generally just exposing
thin wrappers for the underlying system call. This crate offers
a number of common higher level convenience functions.
More recently, there is also an
FileExt available; it currently
just contains an optimized file copy method that will hopefully
go into the standard library.
A wrapper for atomically replacing a file. The primary field
to access here is the
writer. You can also configure the
temporary prefix and suffix used for the temporary file before
it is moved over the final destination.
