Messages

Messages are the fundamental unit of communication in Synaptic. Every interaction with a chat model is expressed as a sequence of Message values, and every response comes back as a Message.

The Message enum is defined in synaptic_core and uses a tagged union with six variants: System, Human, AI, Tool, Chat, and Remove. You create messages through factory methods rather than struct literals.

Quick example

use synaptic::core::{ChatRequest, Message};

let messages = vec![
    Message::system("You are a helpful assistant."),
    Message::human("What is Rust?"),
];

let request = ChatRequest::new(messages);

Guides

• Message Types -- all message variants, factory methods, and accessor methods
• Filter & Trim Messages -- select messages by type/name/id and trim to a token budget
• Merge Message Runs -- combine consecutive messages of the same role into one
