Struct Layer 

pub struct Layer<I: Intercept> { /* private fields */ }

A handler wrapped in a policy: a Serve like any other, registered under the inner handler’s descriptor (with the layer’s name added, outermost first). Built with ErasedHandler::layered.

Trait Implementations

impl<I: Intercept> Serve for Layer<I>

type Family = Dynamic

The family this handler serves, or Dynamic.

fn descriptor(&self) -> HandlerDescriptor

What this handler is: the family-keyed description a typed view checks at bind time and a scene serializes.

fn key(&self) -> HandlerKey

The descriptor’s key. A handler whose descriptor is costly to build, such as a tool’s argument schema, says it without building one.

fn footprint(&self, kind: &EffectKind) -> Option<Touches>

What dispatching kind may read and change, for a tool’s handler (Tool::footprint); None when it cannot say, such as for arguments that do not parse.

fn check(&self, kind: &EffectKind) -> Vec<UnsupportedOption>

The options of kind this handler would leave out when it serves it, with nothing sent: for a model’s handler, what its wire or model cannot honour (DynModel::check). Empty when it leaves nothing out or cannot say, as by default.

async fn serve(&self, kind: EffectKind, dispatch: Dispatch) -> Reply

Prepare an outcome or an owned stream for the driver to consume.
