DynModel

Struct DynModel 

Source
pub struct DynModel(pub Arc<dyn Model>);
Expand description

A concrete newtype wrapping a boxed model, so an Arc<dyn Model> can be used where a concrete M: Model is required (e.g. Subagent::new / AgentLoop<M>).

We deliberately do NOT impl Model for Arc<dyn Model> directly. Doing so changes .stream() method resolution on EVERY Arc<dyn Model> value in the program (from a deref to dyn Model into the Arc impl’s async fn stream RPITIT), and proving that boxed streaming future is Send inside a Send context (e.g. an axum handler driving the streaming loop) overflows the auto-trait solver (E0275). Wrapping in this concrete newtype gives callers DynModel: Model without touching resolution for bare Arc<dyn Model>.

Trait Implementations§

Source§

impl Model for DynModel

Source§

fn complete<'life0, 'life1, 'async_trait>( &'life0 self, ctx: &'life1 Context, ) -> Pin<Box<dyn Future<Output = Result<ModelOutput, ModelError>> + Send + 'async_trait>>
where 'life0: 'async_trait, 'life1: 'async_trait, DynModel: 'async_trait,

Source§

fn stream<'life0, 'life1, 'async_trait>( &'life0 self, ctx: &'life1 Context, ) -> Pin<Box<dyn Future<Output = Result<Pin<Box<dyn Stream<Item = Result<ModelDelta, ModelError>> + Send>>, ModelError>> + Send + 'async_trait>>
where 'life0: 'async_trait, 'life1: 'async_trait, DynModel: 'async_trait,

Streaming is optional; default implementation falls back to complete.
