#prog #rust #rustlib schnellru — A fast and flexible LRU map * Blazingly fast. Up to twice as fast as the lru crate, and with less memory overhead. * Can be also used as an ordered map, with roughly the same performance as indexmap, but with added support for O(1) removals without changing the element order (where indexmap only supports O(n) non-perturbing removals). * Customizable. Out-of-box can be limited by length or by memory usage, but supports custom limiters which can be made to limit the map by whatever you want. * Tested, miri-clean, clippy-clean and fuzzed. * Supports no_std.

Вы не представляете, как я не люблю арты с милыми мальчиками. Среди моих контактов в телеге порядка двадцати они интересны, и я каждый раз забываю переслать кому-то из них 😒

#prog #rust github.com/rust-lang/rust/pull/106400 Ошибки несоответствия типов стали более информативными. 👏 fn bar(_: Vec<i32>) {} fn main() { let v = vec![1, 2, 3, 4, 5]; let mut foo = vec![]; for i in &v { foo.push(i); } bar(foo); } ⬇️ error[E0308]: mismatched types --> src/main.rs:8:9 | 6 | foo.push(i); | - this is of type `&{integer}`, which causes `foo` to be inferred as `Vec<&{integer}>` 7 | } 8 | bar(foo); | --- ^^^ expected `i32`, found `&{integer}` | | | arguments to this function are incorrect

#prog #rust github.com/rust-lang/rust/pull/106519 fn main() { let x = { println!("foo"); 42; }; println!("{}", x); } ⬇️ error[E0277]: `()` doesn't implement `std::fmt::Display` --> src/main.rs:6:20 | 4 | 42; | - help: remove this semicolon 5 | }; 6 | println!("{}", x); | ^ `()` cannot be formatted with the default formatter ❤️

Пока в России на зиму отключают фонтаны, в Японии они зимой мало того что работают, но выглядят даже круче! На видео - пруд в замковом парке в городе Акита.

#prog #3dcg #article Swallowing the elephant into Blender Some years ago Matt Pharr wrote an excellent blog post series, “Swallowing the elephant”, in which he describes various optimizations done in pbrt using Disnay’s Moana Island Scene. Recently I was optimizing Blender’s OBJ importer, and the state of it in the end was “the bottlenecks are not OBJ specific anymore”. I was looking for some larger test scene to import, noticed that the Moana scene got a USD version done in 2022, and started to wonder how well that would import into Blender. So yeah. It takes almost four hours until the import is finished, and then Blender crashes while trying to display it in the viewport. Not quite usable! Here’s a story of random optimizations that I did, and some learnings along the way.
