Our great sponsors
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.

Tree Borrows - A new aliasing model for Rust
It looks like .get_disjoint_mut() from slotmap failed under stacked borrows, but seems to pass under tree borrows

Hey Rustaceans! Got a question? Ask here (5/2023)!
Dunno about existing implementations, but it looks like it's a feature they'd accept: https://github.com/orlp/slotmap/issues/73

Unsafe is a bad practice?
It's actually quite easy.
- Rust is more portable than C for pngquant/libimagequant

Hey Rustaceans! Got an easy question? Ask here (50/2021)!
You can use either slot map or slab to side step rust borrow checker. Example https://github.com/orlp/slotmap/blob/master/examples/rand_meld_heap.rs

Rust data structures with circular references
I don't know, only have some theories.
1. The name isn't particularly catchy or descriptive. It is the correct name for the data structure, but not too many people know the data structure.
2. People don't even know what they're missing. It's not a very Google-able problem to begin with. Slotmap provides an interesting solution to (circular) ownership and safe allocator / weak pointer design problems, but people don't recognize that they're having them or that slotmap could help.
As an example of this, the doubly linked list example (https://github.com/orlp/slotmap/blob/master/examples/doubly_...) can safely remove nodes from the linked list given their handle, in O(1), even from the middle, completely safely and correctly, even in the presence of double deletions or ABA memory re-use. You can't replicate this with just pointers, without introducing heavy refcounting solutions.
Similar to the second approach, you can have better ergonomics and performance by using a memory arena library like slotmap. A doubly linked list implemented using slotmap: https://github.com/orlp/slotmap/blob/ce6e1e02bb2c2074d8d581e...

Is it possible to write anything using 100% safe Rust?
Nope, it's perfectly safe: https://github.com/orlp/slotmap/blob/master/examples/doubly_linked_list.rs.

Syncing HashMap values amongst User
I think keeping the relationship between child and parent elements in the node graph might be better accommodating better via a psuedo-ECS system, see https://www.reddit.com/r/rust/comments/cnjhup/idiomatic_way_to_reference_parent_struct/. The https://github.com/orlp/slotmap crate looks promising. I think I'm just going to ditch the global shared HashMap in favor of something that can better accommodate child/parent relations.

Beginner question: does it become easier to write datastructures with complex ownership semantics?
I think the slotmap crate is similar to what you're trying to write: https://github.com/orlp/slotmap

Is there any part of the Standard Library that really impresses you?
brson had a repository called https://github.com/brson/stdx and it's a pity it isn't maintained anymore: some of them are in disuse now (for example, instead of lazy_static prefer stdlib's Lazy, or better yet, you don't need them if you just want to initialize a mutex or something; also error-chain) and the list could use some maintenance

Nearly 100,000 NPM Users' Credentials Stolen in GitHub OAuth Breach
You suggested creating a super-library of vetted crates. It has been tried before, but it didn’t get any adoption. stdx - The missing batteries of Rust was never used much. Looking at it now, it recommends crates that have been superseded by others.

As an example of the above, if you're not aware of it already, you might find brson/stdx interesting.

Hey, i begin my journey into Rust !
Big libraries like Boost or the Python standard library tend to develop as a workaround for weak package management so, with Cargo, efforts to produce Boost-like compilations (Eg. stdx) withered on the vine for lack of sufficient interest.

First Impressions of Rust
It's been suggested and people even tried doing that of their own volition with projects like stdx, but they withered away for lack of interest.

Hey Rustaceans! Got an easy question? Ask here (50/2021)!
I second u/globulemix' attitude, searching on crates.io and then looking at Downloads and also git activity (might be misleading, as some projects are simply very stable). For a lot of tasks, you might wish to take a look at stdx

Rust Vs. Go Random Observations
I've been here since before Rust 1.0 and I've seen various projects like stdx start, but fail to achieve critical mass... probably because that kind of approach tends to invite the worst kind of bikeshedding.

slab - Slab allocator for Rust
multi_mut - Methods on HashMap and BTreeMap for safely getting multiple mutable references to the contained values.
