Effect<ReadonlyArray<SpanLink>, never, never>Returns the tracing span links currently carried in the effect context.
Details
These links are attached to spans created inside the context. Span links connect related spans without making one span the parent of another.
Example (Providing span links)
import { Effect } from "effect"
const program = Effect.gen(function*() {
// Get the current span links
const links = yield* Effect.spanLinks
console.log(`Current span has ${links.length} links`)
return links
})export const const spanLinks: Effect<
ReadonlyArray<SpanLink>

const spanLinks: {
pipe: { <A>(this: A): A; <A, B = never>(this: A, ab: (_: A) => B): B; <A, B = never, C = never>(this: A, ab: (_: A) => B, bc: (_: B) => C): C; <A, B = never, C = never, D = never>(this: A, ab: (_: A) => B, bc: (_: B) => C, cd: (_: C) => D): D; <…;

spanLinks: 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.
