Enum BodyFrame 

pub enum BodyFrame<D> {
    Data {
        data: D,
        end: bool,
    },
    Headers {
        fields: Fields,
        end: bool,
    },
    End,
}

One owned body event. Initial message fields live in the message head; Headers carries trailing fields, after which no more data is permitted.

end completes this body direction after delivering the payload. End represents completion without a payload, including completion learned after the last data or fields were delivered. It never requires an empty D. An empty data payload with end: false is ordinary data, not completion.
