Kotlin like lazy Grouping API

2

I'm opening this to request/discuss a possible Grouping API like Kotlin's `Grouping`/`groupingBy` API. See Kotlin's [Grouping reference](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/-grouping/) and its [source code](https://github.com/JetBrains/kotlin/blob/master/libraries/stdlib/src/kotlin/collections/Grouping.kt). It would provide an easy way to perform efficient...

The "A Bad but Safe Doubly-Linked Deque" example stops at the `Iter` implementation, mentioning iterator invalidation and that we could pass `Node`s all over the place. I think this is...

`ureq` doesn't expose `CookieStore` and this makes `ureq 2.5.0` a breaking change

1

In order to set cookies in an `AgentBuilder` you need to create a `CookieStore`, however `ureq` doesn't re-export it: to do so you need to explicitly depend on either the...

Add `ReflectFromWorld` and replace the `FromWorld` requirement on `ReflectComponent` and `ReflectBundle` with `FromReflect`

3

# Objective - `FromType` for `ReflectComponent` and `ReflectBundle` currently require `T: FromWorld` for two reasons: - they include a `from_world` method; - they create dummy `T`s using `FromWorld` and then...

The `go!` macro expands the arguments received inside an `unsafe` block, which gives them the ability to do `unsafe` operations even though the user of the macro never used the...

Fix minimal versions

I was trying to compile `bevy` using [`cargo minimal-versions`](https://github.com/taiki-e/cargo-minimal-versions) and noticed that `gpu-allocator` depended on `backtrace 0.3` and `log 0.4`, but actually used features from `backtrace 0.3.3` (`Backtrace::new_unresolved` and `Backtrace::resolve`)...

# Objective - `from_reflect_or_world` is an internal utilty used in the implementations of `ReflectComponent` and `ReflectBundle` to create a `T` given a `&dyn Reflect` by trying to use `FromReflect`, and...

Use rust-lld on windows rustdoc in config_fast_builds.toml

16

# Objective - Rustdoc doesn't seem to follow cargo's `linker` setting - Improves the situation in #12207 ## Solution - Explicitly set the linker in rustdoc flags ## Testing -...

Just a few examples I found very quickly. - `Entity::set` seems to be creating a `&mut T` reference to either uninitialized or zeroed memory (both UB if done for an...

Line intersection loses lot of accuracy
