Infer worker E (failure channel) from effect's Effect return type.

function (type parameter) C in type InferQueueWorkerError<C extends { readonly effect: (...args: any[]) => Effect.Effect<any, any, any>; }>C extends { readonly effect: (

effect: (...args: any[]args: any[]) => import EffectEffect.interface Effect<out A, out E = never, out R = never>The Effect interface defines a value that lazily describes a workflow or
job. The workflow requires some context R, and may fail with an error of
type E, or succeed with a value of type A.
When to use
Use when you need to represent a lazy, composable workflow that can require
services, fail with a typed error, or succeed with a typed value.
Details
Effect values model resourceful interaction with the outside world,
including synchronous, asynchronous, concurrent, and parallel interaction.
They use a fiber-based concurrency model, with built-in support for
scheduling, fine-grained interruption, structured concurrency, and high
scalability.
To run an Effect value, you need a Runtime, which is a type that is
capable of executing Effect values.

? _E
: never
Extracts the error type from an Effect.
When to use
Use to derive the error type from an existing Effect type when declaring
helper types, wrappers, or APIs that preserve the effect's failure channel.
Details
Non-Effect inputs resolve to never.
