2025-06-21rustdoc_json: represent generic args consistently.Nicholas Nethercote-1/+1
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.
2025-06-21rustdoc_json: Add static asserts for the size of important types.Nicholas Nethercote-0/+30
A lot of these are large! Lots of room for improvement in the future.
2025-06-20Rollup merge of #142755 - aDotInTheVoid:rdj-shattrs, r=GuillaumeGomezTrevor Gross-4/+0
rustdoc: Remove `FormatRenderer::cache` We only called it it one place, which isn't generic and can be replaced with a field access.

2025-06-14Auto merge of #142335 - nnethercote:rustdoc-json-allocations, r=aDotInTheVoidbors-19/+29
rustdoc_json: reduce allocations These commits reduce the number of allocations done for rustdoc_json, mostly by avoiding unnecessary clones. Best reviewed one commit at a time. r? `@aDotInTheVoid`
2025-06-11Don't clone `new_item` in `after_krate`.Nicholas Nethercote-7/+16
We can avoid it by using the `entry` API, which lets us do the `assert_eq` comparison before `new_item` is consumed.
2025-06-11Avoid more clones in rustdoc JSON output.Nicholas Nethercote-5/+5
By making `JsonRenderer::item` take `&clean::Item` instead of a `clean::Item`. This required also changing `FromClean` and `IntoJson` methods to take references, which required a lot of follow-on sigil wrangling that is mostly tedious.
2025-06-10Avoid cloning `self.index` in `after_krate`.Nicholas Nethercote-2/+4
It can be very big. This reduces peak memory usage for some `--output-format=json` runs by up to 8%.
2025-06-10Simplify `JsonRenderer`.Nicholas Nethercote-8/+7
- It doesn't need to be cloneable. - Some of the `Rc`s and `RefCell`s aren't doing anything. - `after_krate` can consume `self`.

2025-04-15rustdoc: Output target feature informationWill Glynn-0/+60
`#[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.
2025-03-12rustdoc-json: Extract Id handling into its own moduleAlona Enraght-Moony-10/+2
I want to work on this in a followup commit, so in this commit I make it self-contained. Contains no code changes, all functions are defined exactly as they were in conversions.rs.

Lower them into a single item with multiple resolutions instead. This also allows to remove additional `NodId`s and `DefId`s related to those additional items.
