src/provider.rs

This file is your module map under the providers feature: the one-function profiles, and every piece of HTTP plumbing the clients share.

Key items, profiles

ollama(model), deepseek(), grok(), azure(resource), moonshot(), zai(), and self_hosted(url, model) give you env vars, base URLs, and default models. The overview page tabulates them.

Key items, shared plumbing

HttpClientConfig sets a read timeout of 120s, which is a gap timeout rather than a total cap.

It also covers connect at 10s, pool tuning, tcp_nodelay on for SSE, and an injectable reqwest::Client you can supply.

post_json_checked(...) is your single HTTP-error construction site. It reads Retry-After while the response is in hand, caps error bodies at 8 KB, and classifies: 401 invalid-key, 403 auth, 429 or 503 or 529 rate-limited, else http.

read_bounded_body handles non-streaming response reading and enforces a 10 MB cap.

fold_system_messages(messages, system) pulls inline system messages out and merges them with your configured prompt, caller first, folded appended.

sse_data_payload and sse_event_type are your one-optional-space field parsers.

Behavior notes

azure() validates your resource name before it touches env vars, and only the v1 API surface is supported.

Bodies stay minimal everywhere: empty tool lists are omitted rather than sent as [], and oversized bodies are refused early.
