Detect sysroot dependencies using symlink copy
cc #7637
It is currently in a proof of concept stage, and it doesn't generates a copy. You need to provide your own sysroot copy in `/tmp/ra-sysroot-hack` in a way that `/tmp/ra-sysroot-hack/library/std/lib.rs` exists and `/tmp/ra-sysroot-hack/Cargo.toml` is [the one from this comment](https://github.com/rust-lang/rust-analyzer/issues/7637#issuecomment-1495008329). I will add the symlink code if we decide that this approach is not a dead end.
It seems to somehow work on my system. Go to definition into std dependencies works, type checking can look through fields if I make them public and `cfg_if` appears to work (I tested it by hovering both sides and seeing that the correct one is enabled). Though finding layout of `HashMap` didn't work.
Please try it and let me know if I should go forward in this direction or not.
Restrict "sort items" assist for traits & impls
This restricts the "sort items alphabetically" assist when the selection is inside a `Impl` or `Trait` node & intersects with one of the associated items.
It re-orders the conditional checks of AST nodes in the `sort_items` function to check for more specific nodes first before checking `Trait` or `Impl` nodes. The `AssistContext` is passed into the `add_sort_methods_assist` function to check if the selection intersects with any inner items, e.g. associated const or type alias, function. In this case the assist does not apply.
Fixes: #14516
This fixes the applicability of the "sort items alphabetically" assist
when the selection is inside a `Trait` or `Impl`. It's now tested if the
selection is inside or overlaps with an inner node, e.g. associated
const or type alias, function.
internal: Report macro definition errors on the definition
We still report them on the call site as well for the time being, and the diagnostic doesn't know where the error in the definition comes from, but that can be done later on
Fix explicit deref problems in closure capture
fix the `need-mut` part of #14562
Perhaps surprisingly, it wasn't unique immutable borrow. The code still doesn't emit any of them, and I think those won't happen in edition 2021 (which is currently the only thing implemented), since we always capture `&mut *x` instead of `&mut x`. But I'm not very sure about it.
internal: Warn when loading sysroot fails to find the core library
Should help a bit more with user experience, before we only logged this now we show it in the status
