<S extends Chunk<any>>(self: S): S extends NonEmptyChunk<any>
? RA.NonEmptyReadonlyArray<Chunk.Infer<S>>
: ReadonlyArray<Chunk.Infer<S>>Converts a Chunk into a ReadonlyArray. If the provided Chunk is
non-empty (NonEmptyChunk), the function will return a
NonEmptyReadonlyArray, ensuring the non-empty property is preserved.
Example (Converting chunks to readonly arrays)
import { Chunk } from "effect"
const chunk = Chunk.make(1, 2, 3)
const readonlyArray = Chunk.toReadonlyArray(chunk)
console.log(readonlyArray) // [1, 2, 3]
// The result is read-only, modifications would cause TypeScript errors
// readonlyArray[0] = 10 // TypeScript error
// With empty chunk
const emptyChunk = Chunk.empty<number>()
console.log(Chunk.toReadonlyArray(emptyChunk)) // []converting

RA.NonEmptyReadonlyArray<Chunk.Infer<S>> : ReadonlyArray<Chunk.Infer<S>>S extends interface Chunk<out A>A Chunk is an immutable, ordered collection optimized for efficient concatenation and access patterns.
Example (Inspecting chunk values)
import { Chunk } from "effect"
const chunk: Chunk.Chunk<number> = Chunk.make(1, 2, 3)
console.log(chunk.length) // 3
console.log(Chunk.toArray(chunk)) // [1, 2, 3]
A namespace containing utility types for Chunk operations.
Example (Working with Chunk utility types)
import type { Chunk } from "effect"
// Extract the element type from a Chunk
declare const chunk: Chunk.Chunk<string>
type ElementType = Chunk.Chunk.Infer<typeof chunk> // string
// Create a preserving non-emptiness
declare const nonEmptyChunk: Chunk.NonEmptyChunk<number>
