Trait for LLM providers.
Required Methods§
Sourcefn generate<'life0, 'life1, 'async_trait>(
&'life0 self,
messages: &'life1 [Message],
) -> Pin<Box<dyn Future<Output = Result<Response, LlmError>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
'life1: 'async_trait,
fn generate<'life0, 'life1, 'async_trait>(
&'life0 self,
messages: &'life1 [Message],
) -> Pin<Box<dyn Future<Output = Result<Response, LlmError>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
'life1: 'async_trait,
Generate a complete response (non-streaming).
Sourcefn generate_stream<'life0, 'life1, 'async_trait>(
&'life0 self,
messages: &'life1 [Message],
) -> Pin<Box<dyn Future<Output = Result<Pin<Box<dyn Stream<Item = Result<ResponseChunk, LlmError>> + Send>>, LlmError>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
'life1: 'async_trait,
fn generate_stream<'life0, 'life1, 'async_trait>(
&'life0 self,
messages: &'life1 [Message],
) -> Pin<Box<dyn Future<Output = Result<Pin<Box<dyn Stream<Item = Result<ResponseChunk, LlmError>> + Send>>, LlmError>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
'life1: 'async_trait,
Generate a streaming response.
Sourcefn health_check<'life0, 'async_trait>(
&'life0 self,
) -> Pin<Box<dyn Future<Output = bool> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
fn health_check<'life0, 'async_trait>(
&'life0 self,
) -> Pin<Box<dyn Future<Output = bool> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
Check if the provider is available.
Sourcefn list_models<'life0, 'async_trait>(
&'life0 self,
) -> Pin<Box<dyn Future<Output = Result<Vec<String>, LlmError>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
fn list_models<'life0, 'async_trait>(
&'life0 self,
) -> Pin<Box<dyn Future<Output = Result<Vec<String>, LlmError>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
List models available from this provider. Used by select_provider
to probe reachability and match preferred_models during startup.
Provided Methods§
Sourcefn generate_with_tools<'life0, 'life1, 'life2, 'async_trait>(
&'life0 self,
messages: &'life1 [Message],
tools: &'life2 [ToolDef],
) -> Pin<Box<dyn Future<Output = Result<Response, LlmError>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
'life1: 'async_trait,
'life2: 'async_trait,
fn generate_with_tools<'life0, 'life1, 'life2, 'async_trait>(
&'life0 self,
messages: &'life1 [Message],
tools: &'life2 [ToolDef],
) -> Pin<Box<dyn Future<Output = Result<Response, LlmError>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
'life1: 'async_trait,
'life2: 'async_trait,
Generate with an optional tools channel. Providers that support
function-calling override this to advertise tools and surface any
proposed calls in Response::tool_calls; the default ignores
tools and delegates to generate, so a
chat turn degrades gracefully to a plain text answer on a provider
(or mock) without a tools channel.
Sourcefn fetch_context_window<'life0, 'async_trait>(
&'life0 self,
) -> Pin<Box<dyn Future<Output = Option<usize>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
fn fetch_context_window<'life0, 'async_trait>(
&'life0 self,
) -> Pin<Box<dyn Future<Output = Option<usize>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
Probe the provider for the active model’s context window (in tokens).
Returns None when the provider doesn’t expose this information.
Providers that advertise context_length in their API (OpenRouter,
Ollama) override this for accurate detection; all providers get a
model-name heuristics fallback via [known_context_window].
Dyn Compatibility§
This trait is dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
