Feature request: Packet API that supports writing to a mutable Vec about pdl HOT 4 CLOSED

/// Trait implemented for all toplevel packet declarations.
pub trait Packet: Sized {
    type Parent;

    /// Try parsing an instance of Packet from the its parent representation.
    /// On success, returns the parsed object and the remaining unparsed slice.
    /// On failure, returns an error with the reason for the parsing failure.

    /// behavior of this method is the same as Packet::decode.
