Trait BackendConfig 

pub trait BackendConfig {
    type Args;
    type Id;
    type Kind;
    type Config;
    type Layer;

    // Required methods
    fn config(&self) -> &Self::Config;
    fn middleware(&mut self, worker: &mut WorkerContext) -> Self::Layer;
}

Decorates a backend with middleware, configuration and associated types

Required Associated Types

type Args

The type of argument this backend emits

type Id

The internal type of this Backend’s TaskId

type Kind

This defines the kind of Backend

type Config

The config for the backend

type Layer

The type representing backend middleware layer.

Required Methods

fn config(&self) -> &Self::Config

Returns the config associated with the backend.

fn middleware(&mut self, worker: &mut WorkerContext) -> Self::Layer

Returns the backend’s middleware layer.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
