option-t/esm/nullable/index.js

A toolkit of Nullable/Option/Result type implementation in ECMAScript. Their APIs are inspired by Rust's `Option<T>` and `Result<T, E>`.

// We expose _core primitive_ directly.
export { expectNotNull, isNotNull, isNull, unwrapNullable, } from './core/nullable.js';
// We expose _operators_ (typically named as `~ForNullable`) as bundled.
