Previously, we'd suggest a type of `vec` for a value of type `Vec<T>`,
which is rarely what the user wants. We also had no suggestions for
values of type `&[T]`.
Instead, try to pluralise the inner type name, and fall back to
`items`.
The limit was introduced in https://github.com/rust-lang/rust-analyzer/pull/1408#discussion_r294059044 to avoid infinite cycles but it effectively caps the number of derefs to 10. Types like `ID3D12Device14` from the `windows` crate run into this because it derefs to `ID3D12Device13`, 13 to 12 and so on. Increasing it to 20 is a quick fix; a better cycle detection method would be nicer long term.
Ensure that all the fields that rust-analyzer understands are in the
manual, they all have doc comments, and they use consistent
punctuation (`;` rather than mixing `,` and `;`).
Whilst we're here, fix the `sysroot_src` example and add 2024 as a
legal value for Rust edition.
If the user doesn't have rustc on $PATH, rust-analyzer won't be able
to run `rustc --print cfg`. This isn't really an error, as
rust-analyzer can still proceed without it.
This is particularly noticeable when loading crates defined in a
rust-project.json. Until the configuration is loaded, the opened files
are briefly treated as detached files and users see this error.
Environments with rust-project.json generally have a sysroot and rustc
elsewhere, so the error confuses users.
This time, when completing the keyword (e.g. `fn` + whitespace).
The bug was actually a double-bug:
First, we did not resolve the impl in the macro-expanded file but in the real file, which of course cannot work.
Second, in analysis the whitespace was correlated with the `impl` and not the incomplete `fn`, which caused fake (where we insert an identifier after the whitespace) and real expansions to go out of sync, which failed analysis. The fix is to skip whitespaces in analysis.
the constant is wrong on some platforms (e.g., on mips64el it's 0x10, and 0x8
is RTLD_NOLOAD which makes all this functionality broken), the libc crate takes
care of those differences for us.
fallback to not setting the flag in non-glibc environments - some of them might
have support for it using a different value that we don't know about, and some
of them lack it entirely.
