Struct Anthropic Messages Codec

Generated from cargo doc --no-deps -p nemo-relay -p nemo-relay-adaptive -p nemo-relay-ffi.

Built-in codec for the Anthropic Messages API.

Implements LlmCodec (request decode/encode) and LlmResponseCodec (response decode) for the Anthropic Messages API format.

Anthropic-specific patterns handled

  • Content blocks: Heterogeneous array of text, tool_use, thinking, redacted_thinking, mcp_tool_use, server_tool_use blocks
  • Top-level system: System prompt is a top-level field, not inside messages
  • stop_reason: Maps to FinishReason (not finish_reason)
  • Tool definitions: Uses input_schema instead of parameters
  • Tool choice: {"type":"auto"} / {"type":"any"} / {"type":"tool","name":"..."}
  • Cache tokens: cache_read_input_tokens / cache_creation_input_tokens

Structs

  • AnthropicMessagesCodec: Built-in codec for the Anthropic Messages API.
  • AnthropicMessagesStreamingCodec: Streaming counterpart to AnthropicMessagesCodec.
