Why is the crab not Rust. This is outrageous, it’s unfair

Rust would be some borrow checker compile error like

borrowed data escapes outside of associated function

argument requires that `'1` must outlive `'static`

rust errors are funny if you don't know rust

News at Ten: Borrowed Data Escapes Outside of Associated Function

[–] Ephera@lemmy.ml 8 points 1 day ago (1 children)

Those also happen to be errors you'd typically run into, if you don't yet really know Rust...

[–] d_k_bo@feddit.org 2 points 1 day ago* (last edited 1 day ago)

I do run into them even though I use Rust for ~3 years now, but only in non-obvious cases, e. g. when all references to the borrowed data are dropped before the end of the function.

you can still segfault in rust iirc

[–] jenesaisquoi@feddit.org 1 points 1 day ago (2 children)

Not in safe Rust. Only if you explicitly tell the compiler "I got this, don't worry" but then fuck up.

I guess they fixed the weirdness involving calling main later in the program

[–] Ephera@lemmy.ml 1 points 10 hours ago

As in, you call main() recursively? Don't think, I've ever tried that in any language...
