(name: string, options?: SpanOptionsNoTrace): Effect<Span>Creates a new tracing span and returns it without managing its lifetime.
Details
The span is not added to the current span stack and is not ended
automatically. Use withSpan, useSpan, or makeSpanScoped when the span
should be installed as context or closed automatically.
Example (Creating a span manually)
import { Effect } from "effect"
const program = Effect.gen(function*() {
const span = yield* Effect.makeSpan("my-operation")
yield* Effect.log("Operation in progress")
return "completed"
})export const const makeSpan: (
name: string,
options?: SpanOptionsNoTrace
) => Effect<Span>

makeSpan: (name: stringname: string, options: SpanOptionsNoTraceoptions?: SpanOptionsNoTrace) => 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.
