Struct AnthropicClient 

pub struct AnthropicClient { /* private fields */ }

An Anthropic (Claude) Messages API chat client.

Implementations

impl AnthropicClient

pub fn new(api_key: impl Into<String>, model: impl Into<String>) -> Self

Create a client for the given API key and default model.

pub fn from_env(model: impl Into<String>) -> Result<Self>

Build a client from the ANTHROPIC_API_KEY (and optional ANTHROPIC_BASE_URL) environment variables.

pub fn with_base_url(self, base_url: impl Into<String>) -> Self

Override the base URL (for proxies or private deployments).

pub fn with_max_tokens(self, max_tokens: u32) -> Self

Override the default max_tokens sent when ChatOptions::max_tokens is unset (the Anthropic API requires this field on every request).

pub fn with_default_options(self, options: ChatOptions) -> Self

Set default ChatOptions applied as a base under any options passed per-request (per-request options take precedence; see ChatOptions::merge).

pub fn with_additional_beta_flags( self, flags: impl IntoIterator<Item = impl Into<String>>, ) -> Self

Additional anthropic-beta flags to send (via the anthropic-beta header) on every request, unioned with the always-on convert::DEFAULT_BETA_FLAGS and any per-request flags supplied through ChatOptions::additional_properties["additional_beta_flags"].

Mirrors upstream’s additional_beta_flags constructor keyword argument (_chat_client.py ~126, ~139-140): “Default flags are: mcp-client-2025-04-04, code-execution-2025-08-25.”

pub fn model(&self) -> &str

The default model id.
