Struct LlmProviderFactory 

pub struct LlmProviderFactory;

Factory for creating LLM provider adapters by name.

Each provider is only available when the corresponding feature flag is enabled (openai, anthropic, or deepseek).

Example

use paladin_llm::provider_factory::LlmProviderFactory;

let factory = LlmProviderFactory::new();
let provider = factory.create("openai").expect("OPENAI_API_KEY must be set");

Implementations

impl LlmProviderFactory

pub fn new() -> LlmProviderFactory

Create a new provider factory.

pub fn create( &self, provider_name: &str, ) -> Result<Arc<dyn LlmPort>, ProviderFactoryError>

Create an LlmPort adapter by provider name.

Configuration is loaded from environment variables (see each adapter’s *Config::from_env() for the expected variable names).

Errors

Returns ProviderFactoryError if the provider name is unknown, a required environment variable is absent, or the adapter fails to initialise.

pub fn get_default_provider() -> Option<String>

Return the name of the first available provider based on environment variables, or None if no API keys are set.

Priority: OpenAI → DeepSeek → Anthropic.

pub fn list_available_providers() -> Vec<String>

Return the names of all providers that have API keys configured.

impl Default for LlmProviderFactory

fn default() -> LlmProviderFactory
