Inc is a library which provides writers to write in different formats to files on disk, currently only JSON is supported. incremental_writer::json::IncrementalJsonWriter provides a writer that takes a File writer and incrementally writes JSON objects to an array inside that file using serde_json.

It implements the write trait's write(&[u8]) and flush() as well as write_json() which takes any serialisable object and writes it to the underlying array.
