Required Methods

fn new_appendable_file( &mut self, fname: &String, result: *mut *mut Box<dyn WritableFile>, ) -> Status

| Create an object that either appends to an | existing file, or writes to a new file (if | the file does not exist to begin with). On | success, stores a pointer to the new file in | *result and returns OK. On failure stores | nullptr in *result and returns non-OK. | | The returned file will only be accessed by | one thread at a time. | | May return an IsNotSupportedError error if | this Env does not allow appending to an | existing file. Users of Env (including the | leveldb implementation) must be prepared to | deal with an Env that does not support | appending.
