Package: effect
Module: TxChunk

TxChunk.prepend

Prepends an element to the beginning of the TxChunk.

Details

This function mutates the original TxChunk by adding the element to the beginning. It does not return a new TxChunk reference.

Example (Prepending an element)

import { Chunk, Effect, TxChunk } from "effect"

const program = Effect.gen(function*() {
  const txChunk = yield* TxChunk.fromIterable([2, 3, 4])

  // Add element to the beginning atomically
  yield* TxChunk.prepend(txChunk, 1)

  const result = yield* TxChunk.get(txChunk)
  console.log(Chunk.toReadonlyArray(result)) // [1, 2, 3, 4]
})

Signature

declare const prepend: { <A>(element: A): (self: TxChunk<A>) => Effect.Effect<void>; <A>(self: TxChunk<A>, element: A): Effect.Effect<void>; }
