fix: Remove accidental dependency between `parse_macro_expansion` and `parse`
Turns out my idea from https://github.com/rust-lang/rust-analyzer/pull/15251 causes all builtin derive expansions to obviously rely on the main parse, meaning the entire `macro_arg` layer becomes kind of pointless. So this reverts that PR again.
internal: Implement parent-child relation for `SourceRoot`s
This commit adds the said relation by keeping a map of type `FxHashMap<SourceRootId,Option<SourceRootId>>` inside the `GlobalState`. Its primary use case is reading `rust-analyzer.toml`(#13529) files that can be placed in every local source root. As a config will be found by traversing this "tree" we need the parent information for every local source root. This commit omits defining this relation for library source roots entirely.

fix: panic when using float numbers without dots in chain calls
Fix#16278.
This PR fixes the panic caused by using floating-point numbers without a dot (such as `1e2`) in chain calls.
-------------
Although this syntax is very odd 🤣, r-a should not panic.
fix: keep attributes in assist 'generate_delegate_trait'
fix#15198.
This PR address the issue that `impl` generated by `generate_delegate_trait` doesn't keep attributes.
Add test explorer
This PR implements the vscode testing api similar to #14589, this time using a set of lsp extensions in order to make it useful for clients other than vscode, and make the vscode client side logic simpler (its now around ~100 line of TS code)
Fix#3601
Add `fn index()` and `fn parent_fn()` accessors for `hir::Param`/`hir::SelfParam`
(the PR is motivated by an outside use of the `ra_ap_hir` crate that would benefit from being able to access a `hir::Param`'s/`hir::SelfParam`'s index and parent function)
fix: goto-definition for constants inside range pattern
Fix#15653.
This PR addresses the issue where it was not possible to navigate to constants in range patterns, specifically including two major changes:
1. Previously, both the `start` and `end` fields in `Pat::Range` were of type `LiteralOrConst`. When performing `goto-definition` on constants inside range patterns, r-a would use `resolve_bind_pat_to_const` to find their definitions. However, because the content of a `Const` is not `Pat` but `Path`, it was not stored in the `source_map`, so `resolve_bind_pat_to_const` would returns `None`. This PR changes them to `Const(PatId)`, so that during the lowering process, they are considered as a `pat`, allowing their definitions to be found later through `resolve_bind_pat_to_const`.
2. The process related to range patterns in MIR-lowering has been modified to correctly handle the above changes.
fix: Don't destructure struct with no public fields
Unfortunately I missed this case in #16638.
If a struct only has private members, the assist should not be applicable. Though valid syntax exists (`Foo { .. }`), it isn't particularly useful. Since this case applies to a lot of common types (`Arc`, `Vec`, ...), it probably makes the most sense to hide the action.
As a side effect, this also disables the action for unit structs, where it also isn't particularly useful. I'd be open to changing it though if you think it makes more sense to keep it.
This also fixes the `make::record_pat_field_list` function to produce valid syntax if the field list is empty, as it is used in other places too.
## Current behaviour
```rust
// In crate `other_crate`
pub struct Foo { bar: i32 }
// In current crate
fn do_something(foo: other_crate::Foo) {}
// Becomes
fn do_something(other_crate::Foo { , .. }: other_crate::Foo) {}
```
## Fixed behaviour
Assist should not be applicable in this case anymore.
