feat: do not add new enum if it already exists
## Summary
This PR introduces a check for the existence of another enum within the current scope, and if it exist, we skip `add_enum_def`.
## Why?
Currently, when using the `bool_to_enum` assist more than once, it is possible to add multiple enum definitions. For example, the following snippet,
```rs
#[derive(PartialEq, Eq)]
enum Bool {
True,
False,
}
fn main() {
let a = Bool::True;
let b = true;
println!("Hello, world!");
}
```
will be transformed into,
```rs
#[derive(PartialEq, Eq)]
enum Bool {
True,
False,
}
#[derive(PartialEq, Eq)]
enum Bool {
True,
False,
}
fn main() {
let a = Bool::True;
let b = Bool::True;
println!("Hello, world!");
}
```
This can be annoying for users to clean up.
Add `f16` and `f128` support
Adds `f16` and `f128` support, using the `rustc_apfloat` library (also used by `rustc`) for parsing/arithmetic/displaying since the types aren't stable yet so can't be used by rust-analyzer itself.
Issue: #17451
feat: add inlay hints for generic parameters
fixes#11091
By default, only hints for const generic parameters are shown, and this can be configured through `rust-analyzer.inlayHints.genericParameterHints.enable`.
Probably needs more testing.
Add an option to use "::" for the external crate prefix.
Fixes#11823 .
Hi I'm very new to rust-analyzer and not sure how the review process are. Can somebody take a look at this PR? thanks!
fix: Fix runnables being incorrectly constructed
I've misunderstood parts of the code here which caused runnables to arbitrarily break :) (I have yet to understand the conditions that made them break though, there is some odd caching involved I feel like ...)

internal: Clean up runnable lsp extension
This feels like a natural addition to me, and also allows us to drop the expect-test hardcoding from the extension. Additionally, `cargoExtraArgs` is pointless, all the client will do is merge it with `cargoArgs` so the server can do that instead of delegating that to the client.
fix: Don't emit semantic diagnostics in files with a lot of syntax errors
These will only add to the noise when something very unexpected breaks or where parser recovery fails to kick in.
