option-t/esm/plain_result/to_undefinable.d.ts

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

import type { Undefinable } from '../undefinable/undefinable.js';
import type { Result } from './result.js';
/**
 *  Unwrap `T` if _input_ is `Ok(T)`.
 *  Otherwise, return `undefined`.
 */
export declare function toUndefinableFromOk<T>(input: Result<T, unknown>): Undefinable<T>;
/**
 *  Unwrap `E` if _input_ is `Err(E)`.
 *  Otherwise, return `undefined`.
 */
export declare function toUndefinableFromErr<E>(input: Result<unknown, E>): Undefinable<E>;
