Package: effect
Module: Tuple
Appends a single element to the end of a tuple.
When to use
Use when you need the appended value to remain part of the tuple’s type-level shape and preserve literal element positions.
Details
The result type is [...T, E], preserving all existing element types.
Example (Appending an element)
import { pipe, Tuple } from "effect"
const result = pipe(Tuple.make(1, 2), Tuple.appendElement("end"))
console.log(result) // [1, 2, "end"]
See
appendElements – append multiple elements (another tuple)Signature
declare const appendElement: { <const E>(element: E): <const T extends ReadonlyArray<unknown>>(self: T) => [...T, E]; <const T extends ReadonlyArray<unknown>, const E>(self: T, element: E): [...T, E]; }
