Methods
impl AtomicFile[src]
fn new<P: AsRef<Path>>(path: P, overwrite: OverwriteBehavior) -> Self[src]
Helper for writing to path in write-only mode.
If DisallowOverwrite is given, errors will be returned from self.write(...) if the file
exists.
fn new_with_tmpdir<P: AsRef<Path>>(
path: P,
overwrite: OverwriteBehavior,
tmpdir: P
) -> Self[src]
path: P,
overwrite: OverwriteBehavior,
tmpdir: P
) -> Self
fn path(&self) -> &Path[src]
Get the target filepath.
fn write<T, E, F>(&self, f: F) -> Result<T, Error<E>> where
F: FnOnce(&mut File) -> Result<T, E>, [src]
F: FnOnce(&mut File) -> Result<T, E>,
Open a temporary file, call f on it (which is supposed to write to it), then move the
file atomically to self.path.
