}

Configuration for creating a stateless executor.

Fields

provider: LLMProvider

LLM provider (Anthropic, OpenAI, Google, Cohere, Bedrock).

api_key: String

Provider API credentials.

model: String

Default model for requests.

base_url: Option<String>

Custom base URL for OpenAI-compatible providers. Only used when provider is OpenAI. If None, uses default OpenAI endpoint.

max_tokens: u32

Default max tokens (0 = use DEFAULT_MAX_TOKENS).

system_prompt: Option<String>

Default system prompt (can be overridden per request).

temperature: Option<f32>

Default temperature (None = provider default).

azure_resource: Option<String>

Azure OpenAI resource name (e.g., “my-resource”). When set, the provider uses Azure OpenAI instead of standard OpenAI.

azure_deployment: Option<String>

Azure OpenAI deployment name (e.g., “gpt-4-deployment”).

azure_api_version: Option<String>

Azure OpenAI API version (e.g., “2024-10-21”).

bedrock_region: Option<String>

AWS region for Bedrock (e.g., “us-east-1”).

bedrock_access_key_id: Option<String>

AWS access key ID for Bedrock.

bedrock_secret_access_key: Option<String>

AWS secret access key for Bedrock.

bedrock_session_token: Option<String>

AWS session token for Bedrock (optional, for temporary credentials).

Implementations

impl StatelessConfig

pub fn anthropic( api_key: impl Into<String>, model: impl Into<String>, ) -> StatelessConfig

Creates a new Anthropic config with required fields.

pub fn openai( api_key: impl Into<String>, model: impl Into<String>, ) -> StatelessConfig

Creates a new OpenAI config with required fields.

pub fn openai_compatible( api_key: impl Into<String>, model: impl Into<String>, base_url: impl Into<String>, ) -> StatelessConfig

Creates a new OpenAI-compatible config with a custom base URL.

Use this for providers like Groq, Together, Fireworks, etc. that have OpenAI-compatible APIs.

pub fn google( api_key: impl Into<String>, model: impl Into<String>, ) -> StatelessConfig

Creates a new Google (Gemini) config with required fields.

pub fn azure_openai( api_key: impl Into<String>, resource: impl Into<String>, deployment: impl Into<String>, ) -> StatelessConfig

Creates a new Azure OpenAI config.

Azure OpenAI uses a different URL format and authentication method.

pub fn with_azure_api_version( self, version: impl Into<String>, ) -> StatelessConfig

Sets the Azure API version.

pub fn cohere( api_key: impl Into<String>, model: impl Into<String>, ) -> StatelessConfig

Creates a new Cohere config with required fields.

pub fn bedrock( access_key_id: impl Into<String>, secret_access_key: impl Into<String>, region: impl Into<String>, model: impl Into<String>, ) -> StatelessConfig

Creates a new Amazon Bedrock config.

Arguments

• access_key_id - AWS access key ID
• secret_access_key - AWS secret access key
• region - AWS region (e.g., “us-east-1”)
• model - Bedrock model ID (e.g., “anthropic.claude-3-sonnet-20240229-v1:0”)

pub fn with_bedrock_session_token( self, token: impl Into<String>, ) -> StatelessConfig

Sets the Bedrock session token for temporary credentials.

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

Sets the max tokens.

pub fn with_system_prompt(self, prompt: impl Into<String>) -> StatelessConfig

Sets the system prompt.

pub fn with_temperature(self, temperature: f32) -> StatelessConfig

Sets the temperature.

pub fn validate(&self) -> Result<(), StatelessError>

Validates the config and returns an error if invalid.
