Struct MetadataParts 

pub struct MetadataParts {
    pub version: u8,
    pub config: Config,
    pub frame_count: u64,
    pub last_frame_len: Option<u64>,
    pub raw_lengths: Option<Lengths>,
    pub payload_lengths: Option<Lengths>,
}

External metadata representation. It contains no key and is not self-authenticating. Persist it in trusted storage and restore with Metadata::from_parts.

raw_lengths: Option<Lengths>

Required only for variable logical framing; includes the last frame.

payload_lengths: Option<Lengths>

Required only with compression; excludes tags, includes raw fallbacks.
