They show up in three places: once as `Option<Box<GenericArgs>>`, once
as `Box<GenericArgs>`, and once as `GenericArgs`. The first option is
best. It is more compact because generic args are often missing. This
commit changes the latter two to the former.
Example output, before and after, for the `AssocItemConstraint` change:
```
{"name":"Offset","args":{"angle_bracketed":{"args":[],"constraints":[]}},"binding":{...}}
{"name":"Offset","args":null,"binding":{...}}
```
Example output, before and after, for the `Type::QualifiedPath` change:
```
{"qualified_path":{"name":"Offset","args":{"angle_bracketed":{"args":[],"constraints":[]}}, ...}}
{"qualified_path":{"name":"Offset","args":null, ...}}
```
This reduces JSON output size, but not by much (e.g. 0.5%), because
`AssocItemConstraint` and `Type::QualifiedPath` are uncommon.
`#[target_feature]` attributes refer to a target-specific list of
features. Enabling certain features can imply enabling other features.
Certain features are always enabled on certain targets, since they are
required by the target's ABI. Features can also be enabled indirectly
based on other compiler flags.
Feature information is ultimately known to `rustc`. Rather than force
external tools to track it -- which may be wildly impractical due to
`-C target-cpu` -- have `rustdoc` output `rustc`'s feature data.
rustdoc-json: switch from HashMap to FxHashMap to fix non-determinism
Using `HashMap` in `rustdoc_json_types::Crate` were causing creating randomly ordered objects in the json doc files. Which might cause problems to people who are doing comparison on those files specially in CI pipelines. See https://github.com/rust-lang/rust/issues/103785#issuecomment-1307425590
This PR fixes that issue and extends the coverage of `tests/run-make/rustdoc-verify-output-files` testing ability.
This is needed for json output, but even without that, it increases
performance massivly. On my machine, in reduces the time to check
core.json from 40.190s to 11.333s.
