rustdoc: auto create output directory when "--output-format json"
This PR allows rustdoc to automatically create output directory in case it does not exist (when run with `--output-format json`).
This fixes rustdoc crash:
````
$ rustdoc --output-format json -Z unstable-options src/main.rs
error: couldn't generate documentation: No such file or directory (os error 2)
|
= note: failed to create or modify "doc/main.json"
error: aborting due to previous error
````
With this fix behavior of `rustdoc --output-format json` becomes consistent with `rustdoc --output-format html` (which already auto-creates output directory if it's missing)

Fix errors on blanket impls by ignoring the children of generated impls
Related to #83718
We can safely skip the children, as they don't contain any new info, and may be subtly different for reasons hard to track down, in ways that are consistently worse than the actual generic impl.

Particularly when constructing file paths and fully qualified paths.
This avoids a lot of allocations, speeding things up on almost all
examples.

remove in_band_lifetimes from librustdoc
r? `@camelid`
closes #92368
|

It was previously defined in `render::search_index` but wasn't used at
all there. `clean::types` seems like a better fit since that's where
`ExternalCrate` is defined.
|
|
The old name wasn't very clear, while the new one makes it clear that
this is the code responsible for creating the search index.

rustdoc-json: Don't ignore impls for primitive types
Fix the issue discussed at [Zulip](https://rust-lang.zulipchat.com/#narrow/stream/266220-rustdoc/topic/.E2.9C.94.20Json.20output.20lacks.20some.20item.20which.20are.20supposed.20to.20be.20there)

Previously, rustdoc recorded lifetime bounds by rendering them into the
name of the lifetime parameter. Now, it leaves the name as the actual
name and instead records lifetime bounds in an `outlives` list, similar
to how type parameter bounds are recorded.

This reverts commit 41a345d4c46dad1a98c9993bc78513415994e8ba.

The JSON renderer no longer gets called on modules.
|
|
|
|
|
|
|
|
|
|
It's always `tcx.crate_name(LOCAL_CRATE)`, it doesn't need to be passed
in separately.

[rustdoc] Don't document stripped items in JSON renderer.
Fixes #80664, see [my comment there](https://github.com/rust-lang/rust/issues/80664#issuecomment-797557948) for why
Note that we already do something similar in `convert_item`:

Remove unnecessary `Option` wrapping around `Crate.module`
I'm wondering if it was originally there so that we could `take` the
module which enables `after_krate` to take an `&Crate`. However, the two
impls of `after_krate` only use `Crate.name`, so we can pass just the
name instead.

The rustdoc-json-types renames are breaking changes.

rustdoc: Cleanup `html::render::Context`
- Move most shared fields to `SharedContext` (except for `cache`, which
isn't mutated anyway)
- Replace a use of `Arc` with `Rc`
- Make a bunch of fields private
- Add static size assertion for `Context`
- Don't share `id_map` and `deref_id_map`
|
|
|
|
|
|
|
|
There was no need to clone `id_map` because it was reset before each
item was rendered. `deref_id_map` was not reset, but it was keyed by
`DefId` and thus was unlikely to have collisions (at least for now).
Now we just clone the fields that need to be cloned, and instead create
fresh versions of the others.

transition over hir::ItemKind simpler
|
|
Previously, `JsonRenderer::after_krate` called `krate.version.clone()`.
The problem was it did that after the version was already moved into the
cache, so it would always be None. The fix was to get the version from
the cache instead.
