Struct LLMConfig 

pub struct LLMConfig {
    pub provider: Box<dyn ProviderConfig>,
    pub default_params: DefaultLLMParams,
}

System-wide LLM configuration.

Combines a provider-specific configuration with default model parameters. This is the primary config type used to create a UnifiedLLMClient.

Example

use multi_llm::{LLMConfig, AnthropicConfig, DefaultLLMParams};

let config = LLMConfig {
    provider: Box::new(AnthropicConfig {
        api_key: Some("sk-ant-...".to_string()),
        default_model: "claude-3-5-sonnet-20241022".to_string(),
        ..Default::default()
    }),
    default_params: DefaultLLMParams {
        temperature: 0.7,
        max_tokens: 4096,
        ..Default::default()
    },
};

From Environment

Use from_env() to load from environment variables:

• AI_PROVIDER: Provider name (“anthropic”, “openai”, “ollama”, “lmstudio”)
• Provider-specific vars (e.g., ANTHROPIC_API_KEY, OPENAI_API_KEY)

Fields

provider: Box<dyn ProviderConfig>

The provider-specific configuration.

Contains API keys, endpoints, model selection, and provider features.

default_params: DefaultLLMParams

Default parameters for LLM requests.

Applied to all requests unless overridden by RequestConfig.

Implementations

impl LLMConfig

pub fn create_provider( provider_name: &str, api_key: Option<String>, base_url: Option<String>, model: Option<String>, ) -> LlmResult<Self>

Create configuration for a specific provider with generic parameters This is the main factory method for creating provider configurations

Errors

Returns LlmError::UnsupportedProvider if the provider name is not recognized. Supported providers are: “anthropic”, “openai”, “lmstudio”.

Returns LlmError::ConfigurationError if:

• API key format validation fails
• Provider-specific configuration validation fails
• Required fields for the provider are missing

pub fn from_env() -> LlmResult<Self>

Load configuration from environment variables for the specified provider This is the ONLY method that should access environment variables

Errors

Returns LlmError::ConfigurationError if:

• Required environment variables are missing
• Environment variable values are invalid or malformed
• Provider configuration validation fails

Returns LlmError::UnsupportedProvider if the AI_PROVIDER environment variable contains an unrecognized provider name.
