internal: Defer structured snippet rendering to allow escaping snippet bits
Since we know exactly where snippets are, we can transparently escape snippet bits to the exact text edits that need it, and not have to do it for anything other text edits.
Also will eventually fix#11006 once all assists are migrated. This comes as a side-effect of text edits that don't have snippets get marked as having no insert formatting at all.
Don't provide `add_missing_match_arms` assist when upmapping match arm list failed
Fixes#15310
We shouldn't provide the assist when we fail to find the original match arm list.
Note that this PR will temporarily make the assist not applicable when attribute macro operates on the match expression in question, just like the case in #15310, for most of the current stable toolchain users. This is because the sysroot-abi proc-macro-srv on the current stable [discards] spans for `Group` delimiters in some code paths, which the popular `proc-macro2` crate almost always calls, and it makes the identity of match arm list's brackets lost, leading to the upmapping failure. This has been fixed by #14960, which will land in the next stable, 1.71.

bugfix : skip doc(hidden) default members
fixes #14957 . I have two questions :
1. I am definitely looking for a more idiomatic way for the things I added in `crates/ide-assists/src/utils.rs`. See `FIXME` in that file.
2. Would it be actually better to change `DefaultMethods` to something like
```rust
enum DefaultMethods {
Only( IgnoreHidden ( bool ) ) ,
None
}
```
instead of adding a boolean to every function that calls `crates/ide-assists/src/utils.rs::filter_assoc_items`
fix: Expand eager macros to delimited comma separated expression list
Prior to this, we were just parsing it as an expression which works fine for `()` and `[]` calls as those are tuple and array expressions respectively, but if tails for `{}` calls which with my recent changes reported errors for such eager macro invocations.
Fixup path fragments upon MBE transcription
Fixes#14367
There are roughly two types of paths: paths in expression context, where a separator `::` between an identifier and its following generic argument list is mandatory, and paths in type context, where `::` can be omitted.
Unlike rustc, we need to transform the parsed fragments back into tokens during transcription. When the matched path fragment is a type-context path and is transcribed as an expression-context path, verbatim transcription would cause a syntax error.
This PR fixes up path fragments by inserting `::` to make sure they are syntactically correct in all contexts. Note that this works because expression-context paths are a strict superset of type-context paths.
Add manual implementation of clone for tuples in mir interpreter
And some other minor changes.
Clone for tuple is not implemented in the std and it is magically implemented by the compiler, so we need this.
Properly infer types with type casts
This PR reenables `Expectation::Castable` (previous attempt at #14104, reverted by #14120) and implements type cast checks, which enable us to infer a bit more.
Castable expectations are relatively weak -- they only influence the inference if we cannot infer the types by other means. Therefore, we need to defer possible type unification with the casted type until we type check all expressions of the body. This PR adds a struct and slots in `InferenceContext` for the deferred cast checks (c.f. [`CastCheck`] in `rustc_hir_typeck`).
I only implemented the bits that affect the inference result. It should be possible to return type adjustments for well-formed casts and report diagnostics for invalid casts, but I'm leaving them for future work for now.

vscode: change minimum VS Code version to 1.75 from 1.78
I previously mentioned [in a comment](https://github.com/rust-lang/rust-analyzer/pull/15265#issuecomment-1633240290) that folks at my employer are on 1.78, but I was incorrect: people are on 1.75. I know this is outside the standard version support policy, but I haven't seen any of the new features in VS Code be used in rust-analyzer. The most applicable feature in those three versions of VS Code that I can find [is lazily resolving code actions](https://code.visualstudio.com/updates/v1_78#_resolve-code-action-commands-in-resolvecodeaction), but it doesn't seem like rust-analyzer is making use of that feature.
(I'll be posting a PR that adds support for `$saved_file` within the next day, so feel free to bump the minimum VS Code version back to 1.78 if/when that PR lands. This just makes vendoring the _actual_ change I'm interested in a little bit easier.)
editor/code: Break down CI steps to know what is failing easily
This do the thing I mentioned in https://github.com/rust-lang/rust-analyzer/pull/15265#issuecomment-1634424385
This aims to improve CI status check more readable.
I tried to use [`jobs.<job_id>.if`](https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idif) to make the configuration
more shortly once.
But it could not fire the `end-success` or `end-failure` status if some jobs in the workflow were skipped. This causes an integration problem with bors.
By their reasons, this patch still uses `jobs.<job_id>.steps[*].if`.

To do this change, we reorganize npm-script.
| previous | after |
|--------------------|----------------------------------------|
| `npm run lint` | `npm run lint && npm run format:check` |
| `npm run fix` | `npm run lint:fix && npm run format` |
The previous `npm run fix` sometimes does not complete fix automatically because ESLint's autofix doees not follow prettier's formatting. So we need to run `npm run lint:fix && npm run format` by this order.

limit `change_visibility` assist to applicable items
this pr limits the `change_visibility` assist to applicable items. top level items in this context means items that are not nested within `fn`s or `trait`s.
now
```rs
fn foo {
// assists on this `struct` keyword won't include `change_visibility`
struct Bar {}
}
trait Foo {
// same with the `fn` here
fn bar();
}
```
