    Type Alias Success<VALUE, ERROR>

    A Result is either a Success or a Failure. Both variants are parameterized by BOTH the value and error types so that a chain tracks them precisely: mBind unions the error type as new failures are introduced, or unions the value type as failures recover, and neither ever widens to unknown.

    type Success<VALUE, ERROR> = {
        isSuccess: true;
        value: VALUE;
        either<ON_SUCCESS, ON_FAILURE>(
            onSuccess: (value: VALUE) => ON_SUCCESS,
            onFailure: (reason: ERROR) => ON_FAILURE,
        ): ON_SUCCESS | ON_FAILURE;
        inspect(): string;
        map<NEW_VALUE>(fn: (value: VALUE) => NEW_VALUE): Success<NEW_VALUE, ERROR>;
        mBind<NEW_VALUE, NEW_ERROR>(
            fn: (value: VALUE) => Result<NEW_VALUE, NEW_ERROR>,
        ): Result<NEW_VALUE, ERROR | NEW_ERROR>;
        onComplete(consumer: Consumer<Result<VALUE, ERROR>>): Result<VALUE, ERROR>;
        onFailure(consumer: Consumer<ERROR>): Result<VALUE, ERROR>;
        onSuccess(consumer: Consumer<VALUE>): Result<VALUE, ERROR>;
        or<NEW_ERROR, NEW_VALUE>(
            fn: (reason: ERROR) => Result<NEW_VALUE, NEW_ERROR>,
        ): Result<VALUE | NEW_VALUE, NEW_ERROR>;
        orElse<FALLBACK>(fallback: FALLBACK): VALUE;
        orNull(): VALUE;
        toMaybe(): Some<VALUE>;
    }
