Expand description

The untyped composable-function contract (the LambdaFunction analog) — what the Platform registry stores.

instance is the 1-based worker number (Java parity). Functions must stay stateless and never call other user functions directly — coupling is route-name + envelope only (inv-never-couple-functions).

Required Methods§

Source

fn handle_event<'life0, 'async_trait>( &'life0 self, headers: HashMap<String, String>, input: EventEnvelope, instance: usize, ) -> Pin<Box<dyn Future<Output = Result<EventEnvelope, AppError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
