option-t/esm/plain_result/unsafe/as_mut.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 { MutResult as InternalMutResult } from '../internal/mutable.js';
import type { Result } from '../result.js';
/**
 *  This allows to mutate the value to save needless allocation.
 *
 *  We don't define `MutOk<T>` or `MutErr` because we can always mutable properties on `MutResult<T>`.
 *  This means that it's hard to check the type on static type system.
 */
export type MutResult<T, E> = InternalMutResult<T, E>;
/**
 *  @throws
 *  This throw an `Error` instance if the _input_ is frozen.
