typeTypedArray

typeTypedArray

Matcher for a TypedArray value.

Matchers are applied through assertObjectMatches, where they narrow the corresponding property type.

Type information that already exists in the calling scope is incorporated.

Usage

import { assertObjectMatches, typeTypedArray } from "@kensio/smartass";

const value: unknown = {
  pixels: new Uint8Array([255, 128, 0]),
};

assertObjectMatches(value, {
  pixels: typeTypedArray(),
});

// value is now narrowed to an object with a TypedArray pixels property
// {
//   pixels: TypedArray;
// }
