* refactor(rust): prepare inference and auth foundations * fix(rust): keep textract operations parsing from kebab-case model names Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * done * refactor(types): derive Anthropic beta string conversions with Strum * fix(anthropic): report missing max_tokens as a missing field * refactor(rust): type Anthropic messages headers and auth after the Python layout Delete anthropic/messages/headers.rs. Its OAuth handling, credential ladder and beta merging move to anthropic/common_utils.rs where Python keeps them (optionally_handle_anthropic_oauth, get_auth_header, _merge_beta_headers), and the feature beta injection becomes update_headers_with_anthropic_beta on the messages config, as in Python. The BaseAnthropicMessagesConfig impl is unchanged apart from the bodies of validate_environment and request_headers Beta values are now the AnthropicBeta enum and BetaSet, which sort, dedupe and comma-join by construction. Request params gain typed speed, tools and context_management through Recognized, so the beta logic matches on enums instead of string-comparing JSON. OauthToken parses the sk-ant-oat token once and the chat config shares that detection instead of its own copy Case-insensitive header helpers move next to has_header in litellm-http. One deliberate divergence: a Bearer-prefixed OAuth key configured through api_key or ANTHROPIC_API_KEY is sent with a single Bearer scheme, where Python would emit "Bearer Bearer" Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * done * fix(rust): repair test compilation and clippy failures resolve auth before building the outbound request in prepare tests, give the host hook tests their own error type, and drop the disallowed reqwest client and err().expect() from core tests Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> --------- Co-authored-by: Yujong Lee <yujong@berri.ai> Co-authored-by: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> Co-authored-by: Claude Fable 5.1 <noreply@anthropic.com> |

litellm-router scaffolds the model-list setup and deployment lookup portion of Python's litellm.Router. Router::from_model_list(&config.model_list) maps configured public names to provider deployments. Programmatic callers can collect (String, Deployment) entries into a Router
Lookup is exact and returns None for an unknown name. This extraction preserves the gateway's existing behavior: the last entry wins when public names repeat. Multiple deployments per model group, routing strategies, retries, cooldowns, and fallbacks are not implemented yet
The router owns deployment configuration and selection. The gateway handles HTTP errors and responses, while core executes provider calls and resolves credentials
