Example (Reading queue size)

})export const const size: (

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.
Effect<number> => import TxChunkTxChunk.const size: <A>(
self: TxChunk<A>
) => Effect.Effect<number>
Gets the size of the TxChunk.
Example (Getting the size)
import { Effect, TxChunk } from "effect"
const program = Effect.gen(function*() {
const txChunk = yield* TxChunk.fromIterable([1, 2, 3, 4, 5])
// Get the current size - automatically transactional
const currentSize = yield* TxChunk.size(txChunk)
console.log(currentSize) // 5
// Size is tracked for conflict detection
yield* TxChunk.append(txChunk, 6)
const newSize = yield* TxChunk.size(txChunk)
console.log(newSize) // 6
})
