Type Alias DeepMergeTuple<T>

DeepMergeTuple: T extends [infer First, ...(infer Rest)]
? Rest extends [] ? First : DeepMerge<First, DeepMergeTuple<Rest>>
: unknown

Folds DeepMerge over a tuple of types, merging them left-to-right.

DeepMergeTuple<[A, B, C]> is equivalent to DeepMerge<DeepMerge<A, B>, C>. An empty tuple resolves to unknown; a single-element tuple resolves to that element unchanged.

Type Parameters

T extends any[]
A tuple of types to merge in order.

Example

type A = { x: number };
type B = { y: string };
type C = { z: boolean };
type Merged = DeepMergeTuple<[A, B, C]>;
// Merged = { x: number; y: string; z: boolean }
