You can this. This is currently being done, but not talked about much.

Results vary, so it’s not one of the main courses of interest at the moment.

Be very careful using this over Samba, even with WAL mode enabled. I corrupted an important testing DB this way. Thankfully .recover came to the rescue and only a small amount of data was lost (but the test team had to wait a couple hours for me to bring the test environment back online).

Outer Wilds was accurate!

Wooden spaceships, helmets, and other contraptions, augmented with metals and… other “spoiler” materials.

To anyone interested in space with a day or two to spare, I highly recommend playing Outer Wilds. It’s very good and unlike any other game (and I can’t explain why without spoiling the magic).

Sharing my TypeScript Result type for anyone who’s crazy like me and wishes they had “if let” and doesn’t want “.value” everywhere.

You can do this:

    const user = await fetchUserDTO(123);
    // user is Result<UserDTO, Error>
    if(!isOk(user)) { something(user.err); return; }
    user.name; // user is narrowed to UserDTO

    export const FailSym: unique symbol = (globalThis as any).____FailSym ?? Symbol('FailSym');
    (globalThis as any).____FailSym = FailSym;
    export type Result<T, E> = T | {
        [FailSym]: true,
        err: E
    }
    
    export function Ok<T>(val: T): Result<T, never> { return val; }
    export function Fail<E>(err: E): Result<never, E> { return {[FailSym]: true, err}; }
    
    export function isOk<T, E>(val: Result<T, E>): val is T { return !(typeof val == 'object' && val != null && FailSym in val); }
    export function isFail<T, E>(val: Result<T, E>): val is Result<never, E> { return typeof val == 'object' && val != null && FailSym in val; }
    
    export function resultify<T, E>(promise: Promise<T>): Promise<Result<T, E>> {
        return promise.then(Ok, err => Fail(err as any));
    }
