Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

What's everyone working on this week (42/2021)?
Another brilliant source which I've found is https://github.com/timvisee/advent-of-code-2020. Great inspirational use of iterators there.
-
Hey Rustaceans! Got an easy question? Ask here (12/2021)!
Cool to see the itertools approach here though :) Link to the solution I saw before

This Week in Rust 380
Cool! My first time on TWIR with Solving Advent of Code 2020 in under a second. Though it isn't specifically about Rust, I did use Rust.

[2020] [Rust] Solving Advent of Code 2020 in under a second
The use of a different data structure for the low and high side of the look up table made it faster as described here.

No surprise, Rust is fast.
Oh yes, did Advent of Code in under a second last december, shameless plug đ.

Show HN: Fancy-ANSI â Small JavaScript library for converting ANSI to HTML
Recently did something similar in Rust but for generating SVGs. We've adopted it for snapshot testing of cargo and rustc's output. Don't have a good PR handy for showing Github's rendering of changes in the SVG (text, side-by-side, swiping) but https://github.com/rust-lang/rust/pull/121877/files has newly added SVGs.
To see what is supported, see the screenshot in the docs: https://docs.rs/anstyle-svg/latest/anstyle_svg/

What Are Const Generics and How Are They Used in Rust?
The above Assert<{N % 2 == 1}> requires #![feature(generic_const_exprs)] and the nightly toolchain. See https://github.com/rust-lang/rust/issues/76560 for more info.

Learning Rust: Structuring Data with Structs
Another week, another dive into Rust. This time, we're delving into structs. Structs bear resemblance to interfaces in TypeScript, enabling the grouping of intricate data sets within an object, much like TypeScript/JavaScript. Rust also accommodates functions within these structs, offering a semblance of classes, albeit with distinctions. Let's delve into this topic.

Algorithms for Modern Hardware
Thereâs also other reasons. For example, take binary search:
* prefetch + cmov. These should be part of the STL but languages and compilers struggle to emit the cmov properly (Rustâs been broken for 6 years: https://github.com/rust-lang/rust/issues/53823). Prefetch is an interesting one because while you do optimize the binary search in a micro benchmark, youâre potentially putting extra pressure on the cache with âgarbageâ data which means itâs a greedy optimization that might hurt surrounding code. Probably should have separate implementations as binary search isnât necessarily always in the hot path.
* Eytzinger layout has additional limitations that are often not discussed when pointing out âhey this is fasterâ. Adding elements is non-trivial since you first have to add + sort (as you would for binary search) and then rebuild a new parallel eytzinger layout from scratch (i.e. youâd have it be an index of pointers rather than the values themselves which adds memory overhead + indirection for the comparisons). You canât find the âinsertionâ position for non-existent elements which means it canât be used for std::lower_bound (i.e. if the element doesnât exist, you just get None back instead of Err(position where it can be slotted in to maintain order).
Basically, optimizations can sometimes rely on changing the problem domain so that you can trade off features of the algorithm against the runtime. These kinds of algorithms can be a bad fit for a standard library which aims to be a toolbox of âgood enoughâ algorithms and data structures for problems that appear very very frequently. Or they could be part of the standard library toolkit just under a different name but you also have to balance that against maintenance concerns.
