Struct rustdoc::clean::types::Item

source ·
pub(crate) struct Item {
    pub(crate) name: Option<Symbol>,
    pub(crate) attrs: Box<Attributes>,
    pub(crate) kind: Box<ItemKind>,

}
Expand description

Anything with a source location and set of attributes and, optionally, a name. That is, anything that can be documented. This doesn’t correspond directly to the AST’s concept of an item; it’s a strict superset.

Fields§

§name: Option<Symbol>

The name of this item. Optional because not every item has a name, e.g. impls.

§attrs: Box<Attributes>§kind: Box<ItemKind>

Information about this item that is specific to what kind of item it is. E.g., struct vs enum vs function.

§item_id: ItemId§inline_stmt_id: Option<DefId>

This is the DefId of the use statement if the item was inlined.

§cfg: Option<Arc<Cfg>>

source

pub(crate) fn attr_span(&self, tcx: TyCtxt<'_>) -> Span

source

pub(crate) fn doc_value(&self) -> String

Combine all doc strings into a single value handling indentation and newlines as needed.

source

pub(crate) fn opt_doc_value(&self) -> Option<String>

Combine all doc strings into a single value handling indentation and newlines as needed. Returns None is there’s no documentation at all, and Some("") if there is some documentation but it is empty (e.g. #[doc = ""]).

source

pub(crate) fn from_def_id_and_parts( def_id: DefId, name: Option<Symbol>, kind: ItemKind, cx: &mut DocContext<'_> ) -> Item

source

pub(crate) fn from_def_id_and_attrs_and_parts( def_id: DefId, name: Option<Symbol>, kind: ItemKind, attrs: Box<Attributes>, cfg: Option<Arc<Cfg>> ) -> Item

Find a list of all link names, without finding their href.

This is used for generating summary text, which does not include the link text, but does need to know which []-bracketed names are actually links.
