Struct rustdoc::clean::types::Item

pub(crate) struct Item {
    pub(crate) name: Option<Symbol>,
    pub(crate) attrs: Box<Attributes>,
    pub(crate) visibility: Visibility,
    pub(crate) kind: Box<ItemKind>,
    pub(crate) item_id: ItemId,
    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>

visibility: Visibility

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

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) -> Option<String>

Finds the doc attribute as a NameValue and returns the corresponding value found.

pub(crate) fn from_hir_id_and_parts(
    hir_id: HirId,
    name: Option<Symbol>,
    kind: ItemKind,
    cx: &mut DocContext<'_>
) -> Item

Convenience wrapper around Self::from_def_id_and_parts which converts hir_id to a DefId

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>,
    cx: &mut DocContext<'_>,
    cfg: Option<Arc<Cfg>>
) -> Item

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

Finds all doc attributes as NameValues and returns their corresponding values, joined with newlines.

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 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.

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.
