Module chat 

The chat-wire layer: the ChatMessage/ChatAttachment request model, the lenient and strict parsers that turn an incoming OpenAI/Ollama payload into messages, the outbound payload_value rendering, tool-spec decoding, and the generic ChatML prompt fallback. This is what a gateway uses to bridge a wire request to the kernel’s dispatch surface and back.

Structs

ChatAttachment

A file attached to a chat message: an image forwarded to a vision model, or a document inlined into the prompt text.

ChatMessage

A chat turn: role and content plus optional tool calls, tool-result routing, and attachments.

ChatMlPrompt

The generic ChatML fallback prompt for a model with no chat template.

Enums

AttachmentKind

What kind of thing a ChatAttachment carries.

ChatRole

A chat message’s author.

ChatWireError

Why a chat-wire payload could not be parsed.

Functions

decode_tool_specs

Decode OpenAI-style function tools from a request’s tools value: an array of {type: "function", function: {name, description?, parameters?}}. Absent → empty; malformed → ChatWireError.
