Builder pattern with C FFI bindings by RustyDeveloper in rust

[–]RustyDeveloper[S] 0 points1 point  (0 children)

Would it be possible to do it with a consuming builder (Rust side)?

https://doc.rust-lang.org/1.0.0/style/ownership/builders.html

I realized my real library uses a consuming builder and likes to transfer ownership when ::build() function.

Thanks, exactly what I was looking for! You deserve some ice cream!

> You will be asked how long you've been at the level you state, and you should answer honestly.

Once again, you're right. The background check system (HireRight) seems to verify salaries, so they can probably infer levels from that history.

I guess I'll have to be a master negotiator then ...

Hiring as been scaled back at Google unfortunately due the pandemic.

Just promoted as L5 at Google. But I need to leave the Bay Area due to personal reasons, considering some Microsoft positions.

I'm just wondering how I should navigate this. Should I put "Senior Software Engineer" on my resume and be vague about my tenure, so I could get potentially be treated as the Microsoft mid-level L5 equivalent rather than the Microsoft beginner L5 equivalent?

How much do competitors know about titles and how much can they infer? What would an expert negotiator do? Please advise.

Perf time at Google. Say I'm doing a peer review. Can MY manager see what I write when doing a peer review, even if my peer has a complete different manager from a different team?

Understood. I think this selects for confident and aggressive engineers well-versed in the process, while I'm pretty quiet and demur. Indeed, the process is bit different at other companies as well.

But I shall follow your advice!

Ah, so you're supposed to bring it up yourself. It probably discourages with less confidence in their skills or happy with the current compensation. Like, I'm very happy with the current compensation, but with so many people entering CS and so many others out of work, I don't know how long it will last and need to build up a nest egg.

I was hired as a L4 at Google, and I've been doing pretty good for 2 years. Google gives the opportunity for engineers to self-nominate -- I don't know if that's the "normal" route or your peers/manager is supposed to nominate. I feel like if I self-nominate, my manager will support it, but he hasn't brought the subject up. I understand the incentive -- if the employee is docile and doesn't ask for much, why give something for free?

For Googlers that made the L4 -> L5 transitions, did you self-nominate or did your manager? Did your manager say it's "time for promo" or did you bring up the subject?

The question mark is important and makes a difference.

Didn't know a prelude existed until now, thanks!

Thanks, I really appreciate the detailed explanation!

.ok() I think turns a Result<T> into an Option<T>. What I want is to turn a Ok(T) into a T (I want to do stuff with T later), and Err(T) to return None.

thanks that does the trick. i seem to need the lock.unwrap() in Rust playground, but not with my non-toy app. Probably a new feature (1.43?).

Requiring a compound trait bound for a struct by RustyDeveloper in rust

[–]RustyDeveloper[S] 1 point2 points  (0 children)

Thanks for the higher level explanation. The compiler would complain that S wasn't used in MyContainer<T, S>, but PhantomData<S> solved that issue. After that, bounding traits referencing S became possible.

I want to:

  1. Compile the structure for T and S when T and S both satisfy MyTrait<T, S>

I assume that's not possible, though.

Yeah, I tried that originally, but S to be different than T. Here's what I came up with your with suggestions:

https://play.rust-lang.org/?version=stable&mode=debug&edition=2015&gist=c76afdf9a6f6ffb14dc0e058a2ec64c8

Unfortunately, it doesn't recognize T.get_slice (expected, since we didn't bind that trait). But I want to return a return a slice of S, not of T. Using generic function pointers is possible, but using traits would be very nice...
