Does rust-brotli support self-contained compressed data?

Does this implementation of rust-brotli support a way to have self-contained compressed data as described here? https://www.rfc-editor.org/rfc/rfc7932#section-11.3

This is extremely useful for storing data that you need to be able to seek and only read a small range of bytes.
