Struct AnthropicClient 

pub struct AnthropicClient { /* private fields */ }

Available on crate feature anthropic only.

Anthropic client for Claude models.

Implementations

impl AnthropicClient

pub fn new(config: AnthropicConfig) -> Result<AnthropicClient, AdkError>

Available on crate feature models only.

Create a new Anthropic client.

pub fn from_api_key( api_key: impl Into<String>, ) -> Result<AnthropicClient, AdkError>

Available on crate feature models only.

Create a client with just an API key (uses default model).

pub fn inner(&self) -> &Anthropic

Available on crate feature models only.

Access the underlying adk_anthropic::Anthropic HTTP client.

Use this for direct API access to endpoints not covered by the Llm trait: batches, files, skills, models, token counting, and pricing.

let inner = anthropic_client.inner();
let models = inner.list_models(None).await?;
let batch = inner.create_batch(requests).await?;

pub fn anthropic_config(&self) -> &AnthropicConfig

Available on crate feature models only.

Access the current Anthropic configuration.

pub fn with_retry_config(self, retry_config: RetryConfig) -> AnthropicClient

Available on crate feature models only.

Set the retry configuration (builder pattern).

pub fn set_retry_config(&mut self, retry_config: RetryConfig)

Available on crate feature models only.

Set the retry configuration (mutable reference).

pub fn retry_config(&self) -> &RetryConfig

Available on crate feature models only.

Returns the current retry configuration.

pub async fn latest_rate_limit_info(&self) -> RateLimitInfo

Available on crate feature models only.

Returns the latest rate-limit information from the most recent API response.

Updated after each API call when the server provides rate-limit headers via adk_anthropic::Error::RateLimit or adk_anthropic::Error::ServiceUnavailable. Returns the default (all None) if no rate-limit info has been received.

impl AnthropicClient

pub async fn list_models(&self) -> Result<Vec<ModelInfo>, AdkError>

Available on crate feature models only.

List available Claude models.

Calls GET /v1/models and returns all model descriptors from the first page. For paginated access, use list_models_paginated.

Errors

Returns AdkError::Model with structured error context if the API returns an error.

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

Available on crate feature models only.

Get details for a specific model.

Calls GET /v1/models/{model_id} and returns the model descriptor.

Errors

Returns AdkError::Model with structured error context if the API returns an error (e.g., model not found).

impl AnthropicClient

pub async fn count_tokens( &self, request: &LlmRequest, ) -> Result<TokenCount, AdkError>

Available on crate feature models only.

Count tokens for a request without generating a response.

Calls POST /v1/messages/count_tokens using the same request construction as generate_content, so system prompt extraction, multimodal mapping, and tool conversion all apply.

Errors

Returns AdkError::Model with structured error context if the API returns an error, consistent with the messages API.

Trait Implementations

impl Llm for AnthropicClient

fn name(&self) -> &str

Returns the model identifier (e.g., “gemini-2.5-flash”).

fn schema_adapter(&self) -> &dyn SchemaAdapter

Returns the schema adapter for this provider.

fn generate_content<'life0, 'async_trait>( &'life0 self, request: LlmRequest, stream: bool, ) -> Pin<Box<dyn Future<Output = Result<Pin<Box<dyn Stream<Item = Result<LlmResponse, AdkError>> + Send>>, AdkError>> + Send + 'async_trait>>

where 'life0: 'async_trait, AnthropicClient: 'async_trait,

Generates content from the given request, optionally streaming.

fn uses_interactions_api(&self) -> bool

Returns true if this model is configured to use a server-managed environment (e.g., Gemini Interactions API) where the provider owns the tool-calling loop and filesystem.
