Struct ErasedHandler 

pub struct ErasedHandler(/* private fields */);

Shared, type-erased handler. Clones retain the same handler allocation. Implements Send + Sync on native targets, but not on WASM.

Implementations

impl ErasedHandler

pub fn new(handler: impl Serve + 'static) -> Self

Erase handler.

pub fn layered(self, intercept: impl Intercept) -> Self

Wrap this handler in a Layer: intercept sees every dispatch before this handler does and every answer after. handler.layered(a).layered(b) calls b.before first and a.after first.

pub fn descriptor(&self) -> HandlerDescriptor

What the erased handler is.

pub fn handle(&self, kind: EffectKind, dispatch: Dispatch) -> HandlerFuture<'_>

Serve one effect: the driver’s call, straight to the boxed handler.

pub fn ptr_eq(&self, other: &Self) -> bool

Whether two erased handlers are the same allocation.

Trait Implementations

impl Clone for ErasedHandler

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ErasedHandler

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Serve for ErasedHandler

Forwards serving to the wrapped handler; re-erasure adds another boxed future.

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.

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

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