Struct SpawnerStack 

Source 
pub struct SpawnerStack { /* private fields */ }
Expand description

Stack builder that layers SpawnerLayers on top of a base adapter.

Each .layer(...) call wraps a new outer stage — same ergonomics as tower::ServiceBuilder.

Implementations§

Source§

impl SpawnerStack

Source

pub fn new(base: Arc<dyn SpawnerAdapter>) -> Self

Starts a stack with base as the innermost adapter.

Source

pub fn layer<L: SpawnerLayer>(self, layer: L) -> Self

Wraps the current stack with a statically-typed SpawnerLayer, becoming the new outermost stage.

Source

pub fn layer_dyn(self, layer: Arc<dyn SpawnerLayer>) -> Self

Dynamically-typed variant taking Arc<dyn SpawnerLayer>. Used via the LayerRegistry resolution path (where a factory returns Arc<dyn ...>).

Source

pub fn build(self) -> Arc<dyn SpawnerAdapter> ⓘ

Finishes the stack, returning the fully-wrapped adapter.
