Don't mark `#[rustc_deprecated_safe_2024]` functions as unsafe
`std::env::set_var` will be unsafe in edition 2024, but not before it. I couldn't quite figure out how to check for the span properly, so for now we just turn the false positives into false negatives, which are less bad.

Allow sysroots to only consist of the source root dir
Fixes https://github.com/rust-lang/rust-analyzer/issues/17159
This PR encodes the `None` case of an optional sysroot into `Sysroot` itself. This simplifies a lot of things and allows us to have sysroots that consist of nothing, only standard library sources, everything but the standard library sources or everything. This makes things a lot more flexible. Additionally, this removes the workspace status bar info again, as it turns out that that can be too much information for the status bar to handle (this is better rendered somewhere else, like in the status view).
Fix: infer type of async block with tail return expr
Fixes#17106
The `infer_async_block` method calls the `infer_block` method internally, which returns the never type without coercion when `tail_expr` is `None` and `ctx.diverges` is `Diverges::Always`.This is the reason for the bug in this issue.
cfce2bb46d/crates/hir-ty/src/infer/expr.rs (L1411-L1413)
This PR solves the bug by adding a process to coerce after calling `infer_block` method.
This code passes all the tests, including tests I added for this isuue, however, I am not sure if this solution is right. I think that this solution is an ad hoc solution. So, I would appreciate to have your review.
I apologize if I'm off the mark, but `infer_async_block` method should be rewritten to share code with the process of infering type of `expr::Closure` instead of the `infer_block` method. That way it will be closer to the infer process of rustc.
feat: More callable info
With this PR we retain more info about callables other than functions, allowing for closure parameter type inlay hints to be linkable as well as better signature help around closures and `Fn*` implementors.
When viewing traces, it's slightly confusing when the span name doesn't
match the function name. Ensure the names are consistent.
(It might be worth moving most of these to use #[tracing::instrument]
so the name can never go stale. @davidbarsky suggested that is marginally
slower, so I've just done the simple change here.)
Instead of using `core::fmt::format` to format panic messages, which may in turn
panic too and cause recursive panics and other messy things, redirect
`panic_fmt` to `const_panic_fmt` like CTFE, which in turn goes to
`panic_display` and does the things normally. See the tests for the full
call stack.
