This is a precursor to the possibility of a more extensive Atomic File I/O system. For now it simply provides a means for atomic file writing.
Write to a file atomically. Useful for situations where you don‘t want other processes or threads to see half-written files.
AtomicFile.write("tmp/important.file") do |file| file.write("hello") end
If your temporary directory is not on the same filesystem as the file you‘re trying to write, you can provide a different temporary directory.
AtomicFile.write("tmp/something.important", "tmp") do |file| file.write("hello") end
