option-t/esm/plain_result/inspect.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>`.

 *  * Call _effector_ with the inner value of _input_ if _input_ is `Ok(T)`.
 *  * This main purpose is to inspect an inner value in a chained function calling.
 *    If you don't have to do it, you should not mutate the inner value.
 *    if-else statement might be sufficient to mutate the inner value instead of calling this function.
