Struct FnClientCallback 

pub struct FnClientCallback<F, E>
where
    F: Fn(&CallbackRequest, &[PayloadEnvelope]) -> Result<CallbackResponse, E>,
{ /* private fields */ }

Adapter that lifts any Fn(&CallbackRequest, &[PayloadEnvelope]) -> Result<CallbackResponse, E> into a ClientCallback.

The fake-client tests stand up a ClientCallback inline through this type without IO.

Implementations

impl<F, E> FnClientCallback<F, E>

where F: Fn(&CallbackRequest, &[PayloadEnvelope]) -> Result<CallbackResponse, E>,

pub fn new(f: F) -> Self

Trait Implementations

impl<F, E> ClientCallback for FnClientCallback<F, E>

where F: Fn(&CallbackRequest, &[PayloadEnvelope]) -> Result<CallbackResponse, E>,

type Error = E

Error produced by the client transport. Kept generic so an in-process impl, a renderer-backed impl, and a network impl can each carry their own diagnostic shape.

fn dispatch( &self, request: &CallbackRequest, payloads: &[PayloadEnvelope], ) -> Result<CallbackResponse, Self::Error>

Deliver request (alongside any opaque payloads) to the client and return its CallbackResponse.
