Struct Anthropic 

pub struct Anthropic { /* private fields */ }

Client for the Anthropic API with performance optimizations.

Implementations

impl Anthropic

pub fn new(api_key: Option<String>) -> Result<Self>

Create a new Anthropic client.

The API key can be provided directly or read from the CLAUDIUS_API_KEY or ANTHROPIC_API_KEY environment variables. If an environment variable value starts with “file://”, it will be treated as a file path and the API key will be read from that file.

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

Set a custom base URL for this client.

This method allows you to specify a different API endpoint for the client.

pub fn with_timeout(self, timeout: Duration) -> Result<Self>

Set a custom timeout for this client.

This method allows you to specify a different timeout for API requests.

pub fn with_max_retries(self, max_retries: usize) -> Self

Set the maximum number of retries for this client.

This method allows you to specify how many times to retry failed requests.

pub fn api_key(&self) -> &str

Get the API key being used by this client.

pub fn with_backoff_params( self, throughput_ops_sec: f64, reserve_capacity: f64, ) -> Self

Set the backoff parameters for this client.

This method allows you to configure the exponential backoff algorithm.

pub fn with_base_url_and_timeout( self, base_url: String, timeout: Duration, ) -> Result<Self>

Set both a custom base URL and timeout for this client.

This is a convenience method that chains with_base_url and with_timeout.

pub async fn send(&self, params: MessageCreateParams) -> Result<Message>

Send a message to the API and get a non-streaming response.

pub async fn stream( &self, params: MessageCreateParams, ) -> Result<impl Stream<Item = Result<MessageStreamEvent>>>

Send a message to the API and get a streaming response.

Returns a stream of MessageStreamEvent objects that can be processed incrementally.

pub async fn count_tokens( &self, params: MessageCountTokensParams, ) -> Result<MessageTokensCount>

Count tokens for a message.

This method counts the number of tokens that would be used by a message with the given parameters. It’s useful for estimating costs or making sure your messages fit within the model’s context window.

pub async fn list_models( &self, params: Option<ModelListParams>, ) -> Result<ModelListResponse>

List available models from the API.

Returns a paginated list of all available models. Use the parameters to control pagination and filter results.

pub async fn get_model(&self, model_id: &str) -> Result<ModelInfo>

Retrieve information about a specific model.

Returns detailed information about the specified model, including its ID, creation date, display name, and type.
