Struct AgentSpawnerFn 

pub struct AgentSpawnerFn(pub Box<dyn Fn(AgentConfig) -> Pin<Box<dyn Future<Output = Result<SpawnedAgent, SpawnError>> + Send>> + Send + Sync>);

Phase 81.32 c6 — sized newtype wrapping the type-erased spawner closure stored by crate::config_reload::ConfigReloadCoordinator.

ArcSwapOption<T> requires T: Sized so we wrap the unsized dyn Fn(…) in a Box and the newtype around the Box. The coordinator stores ArcSwapOption<AgentSpawnerFn> and invokes via spawner.0(cfg).

Boxed-future return because async fn in a trait/closure produces an opaque future type the coordinator can’t name without GATs.

Lives in spawn (vs config_reload) so the field type on ConfigReloadCoordinator doesn’t pull every per-agent dep the closure captures into the coordinator’s API surface.

Implementations

impl AgentSpawnerFn

pub fn call( &self, cfg: AgentConfig, ) -> Pin<Box<dyn Future<Output = Result<SpawnedAgent, SpawnError>> + Send>>

Convenience: invoke the wrapped closure directly without touching the .0 field at every call site.
