}Expand description
Unified interface for LLM providers.
Implement this trait to add a new model provider.
The system string returned by system_name() is used as the
gen_ai.system OTel attribute.
Required Methods§
Sourcefn system_name(&self) -> &'static str
fn system_name(&self) -> &'static str
OTel GenAI system name (e.g. “anthropic”, “openai”).
Sourcefn default_model(&self) -> &str
fn default_model(&self) -> &str
Default model for this adapter (e.g. “claude-sonnet-4-6”).
Sourcefn chat<'life0, 'async_trait>(
&'life0 self,
request: ModelRequest,
) -> Pin<Box<dyn Future<Output = Result<ModelResponse, ModelError>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
fn chat<'life0, 'async_trait>(
&'life0 self,
request: ModelRequest,
) -> Pin<Box<dyn Future<Output = Result<ModelResponse, ModelError>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
Send a chat request and return the response.
Sourcefn structured_output<'life0, 'async_trait>(
&'life0 self,
request: StructuredRequest,
) -> Pin<Box<dyn Future<Output = Result<ModelResponse, ModelError>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
fn structured_output<'life0, 'async_trait>(
&'life0 self,
request: StructuredRequest,
) -> Pin<Box<dyn Future<Output = Result<ModelResponse, ModelError>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
Send a structured output request, returning a JSON value.
The response is validated against request.output_schema if possible.
Dyn Compatibility§
This trait is dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
