Hey Nathan, thanks for still making this video with all the sponsor stuff in mind. I would completely understand if you declined to continue this series (too many people who burn out dedicating their lives to something like this for nothing in return), but it is highly enjoyable content.

@JamesHarrisonHaribo 15 дней назад

I really did like the more in-depth walkthrough of all changes version-to-version, it was hugely informative.

@NathanStocks 15 дней назад

So did I! As I get more sponsors, I will increase the length of my videos. With enough sponsors I would love to start making more frequent videos about other Rust news and topics as well.

Does the tuple collect() means that one can collect into nested tuples? That's quite cool

@NathanStocks 15 дней назад

I tried it...and YES! fn main() { let input = vec![1, 2, 3, 4, 5]; let ((doubled, tripled), squared): ((Vec, Vec), Vec) = input.iter().map(|x| ((x * 2, x * 3), x * x)).collect(); assert_eq!(doubled, [2, 4, 6, 8, 10]); assert_eq!(tripled, [3, 6, 9, 12, 15]); assert_eq!(squared, [1, 4, 9, 16, 25]); }

i had a good laugh at number 8 haha

@NathanStocks 15 дней назад

😄

@pfeilspitze 15 дней назад

Hopefully 8 is smart enough to not warn on constants from other crates, where no, I don't know if it's empty.

@NathanStocks 15 дней назад

I have so many questions about your comment! 😂 First, why did the library author export an empty constant? I have never seen that! Second, why do you need to check if the library’s constant is empty? Third, you imply that you would rather call is_empty at runtime than peek at the value of the constant after a lint tells you about it-why?

@pfeilspitze 15 дней назад

@@NathanStocks Because if it's a constant in another crate it can change, so checking once doesn't work. Maybe it's a constant from a build-time environment variable, or something. It's like how `char::UNICODE_VERSION < (16, 0, 0)` is true right now, but probably soon won't be, and clippy would be very wrong to tell me not to check it and just remove the else.

Huh, interesting.

13 And no man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven. 14 And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up: 15 That whosoever believeth in him should not perish, but have eternal life. 16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. 17 For God sent not his Son into the world to condemn the world; but that the world through him might be saved. 18 He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God. 19 And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil. 20 For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved. 21 But he that doeth truth cometh to the light, that his deeds may be made manifest, that they are wrought in God. (Jn.3:13-21)
