gtp-protocol

Group Text Protocol — text-messaging sub-protocol of the Group Protocol Stack.

GTP is to GBP what TCP is to IP: it adds idempotent message-level semantics on top of the GBP base layer's framing and AEAD.

What this crate provides

• GtpMessage — the text message envelope; can be encoded as CBOR, Protobuf, or FlatBuffers (selected by PayloadCodec).
• GtpClient — stateful client that:
  • sends text messages through a gbp_node::GroupNode with a caller-chosen PayloadCodec (default Cbor for backward compat);
  • accepts incoming plaintext payloads delivered by GBP (codec echoed from the payload_received event) and rejects duplicates by (sender_id, message_id).

Example

use gtp::GtpClient;

let mut client = GtpClient::new();
let frame = client.send(&mut node, &mut sealer, target, 0xCAFE_F00D, "hello")?;
// hand `frame.wire` to your transport...
