Function write_atomic::write_file

pub fn write_file<P>(src: P, data: &[u8]) -> Result<()> where
    P: AsRef<Path>, 

Atomic File Write!

This will write bytes atomically to the specified path, maintaining permissions and ownership if it already exists, or creating it anew using the same default permissions and ownership std::fs::File::create would.

Atomicity is achieved by first writing the content to a temporary location. On most Linux systems, this will use O_TMPFILE; for other systems, the tempfile crate will be used instead.

Examples

// It's just one line:
write_atomic::write_file("/path/to/my/file.txt", b"Some data!")
    .unwrap();

Errors

This will bubble up any filesystem-related errors encountered along the way.
