Build Status

Atomic file-writes to POSIX filesystems. The basic idea is to write to temporary files, and move them when done writing. This avoids the problem of two programs writing to the same file. For AllowOverride, link + unlink is used instead of rename to raise errors when the target path already exists.

Example

use atomicwrites::{AtomicFile,DisallowOverwrite};

let af = AtomicFile::new(&Path::new("foo"), DisallowOverwrite, None);
try!(af.write(|&: f| {
    f.write_str("HELLO")
}));
