rustdoc: make settings checkboxes always square
Previously, checkboxes would flex horizontally on small screens:
this simple css tweak fixes this.
|
|
|
|
|
|
|
|
this allows us to eliminate the last 3 @ts-expect-error
in this file.
|
|
"true" looks like a string value, `true` makes it more clear
that we are talking about the actual boolean value.
|
|
With this, almost the entire file is fully typechecked,
the only exception being the Element.contains(EventTarget) pattern
that is used several times, those are annotated with
@ts-expect-error
|
|
|
|
changes:
* Add type signature
* Add null checks
* getHelpButton and getSettingsButton are only called once,
which should marginally improve performance due to less queries.
unfortunatly 2 @ts-expect-error was needed,
as typescript is unaware the EventTarget is likely an Element.

this also makes `changeSetting` more robust in case it somehow
gets called before `main.js` has finished loading.

Move methods from `Map` to `TyCtxt`, part 5.
This eliminates all methods on `Map`. Actually removing `Map` will occur in a follow-up PR.
A follow-up to #137504.

`ast::Item` has an `ident` field.
- It's always non-empty for these item kinds: `ExternCrate`, `Static`,
`Const`, `Fn`, `Mod`, `TyAlias`, `Enum`, `Struct`, `Union`,
`Trait`, `TraitAlias`, `MacroDef`, `Delegation`.
- It's always empty for these item kinds: `Use`, `ForeignMod`,
`GlobalAsm`, `Impl`, `MacCall`, `DelegationMac`.
There is a similar story for `AssocItemKind` and `ForeignItemKind`.
Some sites that handle items check for an empty ident, some don't. This
is a very C-like way of doing things, but this is Rust, we have sum
types, we can do this properly and never forget to check for the
exceptional case and never YOLO possibly empty identifiers (or possibly
dummy spans) around and hope that things will work out.
The commit is large but it's mostly obvious plumbing work. Some notable
things.
- `ast::Item` got 8 bytes bigger. This could be avoided by boxing the
fields within some of the `ast::ItemKind` variants (specifically:
`Struct`, `Union`, `Enum`). I might do that in a follow-up; this
commit is big enough already.
- For the visitors: `FnKind` no longer needs an `ident` field because
the `Fn` within how has one.
- In the parser, the `ItemInfo` typedef is no longer needed. It was used
in various places to return an `Ident` alongside an `ItemKind`, but
now the `Ident` (if present) is within the `ItemKind`.
- In a few places I renamed identifier variables called `name` (or
`foo_name`) as `ident` (or `foo_ident`), to better match the type, and
because `name` is normally used for `Symbol`s. It's confusing to see
something like `foo_name.name`.

rustc_resolve: fix instability in lib.rmeta contents
rust-lang/rust@23032f31c91f2 accidentally introduced some nondeterminism in the ordering of lib.rmeta files, which we caught in our bazel-based builds only recently due to being further behind than normal. In my testing, this fixes the issue.

Greatly simplify doctest parsing and information extraction
The original process was pretty terrible, as it tried to extract information such as attributes by performing matches over tokens like `#!`, which doesn't work very well considering you can have `# ! [`, which is valid.
Also, it now does it in one pass: if the parser is happy, then we try to extract information, otherwise we return early.

This removes the `--enable-per-target-ignores` and enables it
unconditionally.
|
|
|
|
This renames `--runtool` and `--runtool-arg` to `--test-runtool` and
`--test-runtool-arg` to maintain consistency with other `--test-*`
arguments.

specifically, `storage.js` is not loaded during `rustdoc-js`
and `rustdoc-js-std` tests.

"Missing" patterns are possible in bare fn types (`fn f(u32)`) and
similar places. Currently these are represented in the AST with
`ast::PatKind::Ident` with no `by_ref`, no `mut`, an empty ident, and no
sub-pattern. This flows through to `{hir,thir}::PatKind::Binding` for
HIR and THIR.
This is a bit nasty. It's very non-obvious, and easy to forget to check
for the exceptional empty identifier case.
This commit adds a new variant, `PatKind::Missing`, to do it properly.
The process I followed:
- Add a `Missing` variant to `{ast,hir,thir}::PatKind`.
- Chang `parse_param_general` to produce `ast::PatKind::Missing`
instead of `ast::PatKind::Missing`.
- Look through `kw::Empty` occurrences to find functions where an
existing empty ident check needs replacing with a `PatKind::Missing`
check: `print_param`, `check_trait_item`, `is_named_param`.
- Add a `PatKind::Missing => unreachable!(),` arm to every exhaustive
match identified by the compiler.
- Find which arms are actually reachable by running the test suite,
changing them to something appropriate, usually by looking at what
would happen to a `PatKind::Ident`/`PatKind::Binding` with no ref, no
`mut`, an empty ident, and no subpattern.
Quite a few of the `unreachable!()` arms were never reached. This makes
sense because `PatKind::Missing` can't happen in every pattern, only
in places like bare fn tys and trait fn decls.
I also tried an alternative approach: modifying `ast::Param::pat` to
hold an `Option<P<Pat>>` instead of a `P<Pat>`, but that quickly turned
into a very large and painful change. Adding `PatKind::Missing` is much
easier.

Remove `kw::Empty` uses from `rustc_middle`.
There are several places in `rustc_middle` that check for an empty lifetime name. These checks appear to be totally unnecessary, because empty lifetime names aren't produced here. (Empty lifetime names *are* possible in `hir::Lifetime`. Perhaps there was some confusion between it and the `rustc_middle` types?)
This commit removes the `kw::Empty` checks.

rustdoc: Rearrange `Item`/`ItemInner`.
The `Item` struct is 48 bytes and contains a `Box<ItemInner>`;
`ItemInner` is 104 bytes. This is an odd arrangement. Normally you'd
have one of the following.
- A single large struct, which avoids the allocation for the `Box`, but
can result in lots of wasted space in unused parts of a container like
`Vec<Item>`, `HashSet<Item>`, etc.
- Or, something like `struct Item(Box<ItemInner>)`, which requires the
`Box` allocation but gives a very small Item size, which is good for
containers like `Vec<Item>`.
`Item`/`ItemInner` currently gets the worst of both worlds: it always
requires a `Box`, but `Item` is also pretty big and so wastes space in
containers. It would make sense to push it in one direction or the
other. #138916 showed that the first option is a regression for rustdoc,
so this commit does the second option, which improves speed and reduces
memory usage.
