Struct Messages 

pub struct Messages { /* private fields */ }

client.messages() — Anthropic-format pass-through (spec §9).

Implementations

impl Messages

pub async fn create(&self, params: impl Serialize) -> Result<Value, Error>

Anthropic-format message (POST /v1/messages) — the wire format used by the anthropic SDKs and Claude Code.

Accepts the standard Anthropic Messages request fields (model, max_tokens, messages, system, tools, …) verbatim and returns the raw Anthropic-shaped response object. Works with every gateway model, not just Claude — the gateway bridges the wire format.

pub async fn create_stream( &self, params: impl Serialize, ) -> Result<RawEventStream, Error>

Streaming Anthropic-format message.

Sets stream: true on the body (all other fields pass through verbatim) and returns a RawEventStream of raw Anthropic stream events (message_start … message_stop). There is no [DONE] — a healthy stream ends with a message_stop event followed by EOF; EOF before message_stop surfaces Error::ModelStreamError; an error event aborts with the §4-mapped error.

pub async fn count_tokens(&self, params: impl Serialize) -> Result<Value, Error>

Anthropic-format token counting (POST /v1/messages/count_tokens).

Returns the raw response object ({"input_tokens": …}). Token counting is free — no inference happens.
