<A extends Any>(

When to use
Use when you need a RequestResolver to complete an entry with structured
cause information rather than only the request's typed error value.

A utility type to extract the error type from a Request.
Example (Extracting a request error type)
import type { Request } from "effect"
interface GetUser extends Request.Request<string, Error> {
readonly id: number
}
// Extract the error type from a Request using the utility

interface Entry<out R>A pending request handed to a RequestResolver.
Details
An entry contains the original request, the fiber context needed to run it,
an uninterruptible flag used by batching and caching internals, and the
completeUnsafe callback used by resolvers to supply the final Exit.
