Struct rustdoc::clean::types::Item

pub(crate) struct Item {
    pub(crate) name: Option<Symbol>,
    pub(crate) attrs: Box<Attributes>,
    pub(crate) kind: Box<ItemKind>,
    pub(crate) item_id: ItemId,
    pub(crate) inline_stmt_id: Option<DefId>,
    pub(crate) cfg: Option<Arc<Cfg>>,
}

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>>

Implementations

impl Item

pub(crate) fn stability<'tcx>(&self, tcx: TyCtxt<'tcx>) -> Option<Stability>

pub(crate) fn const_stability<'tcx>( &self, tcx: TyCtxt<'tcx> ) -> Option<ConstStability>

pub(crate) fn deprecation(&self, tcx: TyCtxt<'_>) -> Option<Deprecation>

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

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

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

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

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

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 = ""]).

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

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

pub(crate) fn links(&self, cx: &Context<'_>) -> Vec<RenderedLink>

pub(crate) fn link_names(&self, cache: &Cache) -> Vec<RenderedLink>

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.

pub(crate) fn const_stable_since(&self, tcx: TyCtxt<'_>) -> Option<Symbol>

pub(crate) fn is_non_exhaustive(&self) -> bool

pub(crate) fn type_(&self) -> ItemType

Returns a documentation-level item type from the item.

pub(crate) fn is_default(&self) -> bool

pub(crate) fn fn_header(&self, tcx: TyCtxt<'_>) -> Option<FnHeader>

Returns a FnHeader if self is a function item, otherwise returns None.

pub(crate) fn visibility(&self, tcx: TyCtxt<'_>) -> Option<Visibility<DefId>>

Returns the visibility of the current item. If the visibility is “inherited”, then None is returned.

pub(crate) fn attributes( &self, tcx: TyCtxt<'_>, keep_as_is: bool ) -> Vec<String>

pub fn is_doc_hidden(&self) -> bool

pub fn def_id(&self) -> Option<DefId>

Trait Implementations

impl Clone for Item

fn clone(&self) -> Item

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Item

NOTE: this does NOT unconditionally print every item, to avoid thousands of lines of logs. If you want to see the debug output for attributes and the kind as well, use {:#?} instead of {:?}.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> From<&'a Item> for ItemType

fn from(item: &'a Item) -> ItemType

Converts to this type from the input type.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
