Struct Item

pub struct Item {
    pub id: Id,
    pub crate_id: u32,
    pub name: Option<String>,
    pub span: Option<Span>,
    pub visibility: Visibility,
    pub docs: Option<String>,
    pub links: HashMap<String, Id>,
    pub attrs: Vec<String>,
    pub deprecation: Option<Deprecation>,
    pub inner: ItemEnum,
}

Anything that can hold documentation - modules, structs, enums, functions, traits, etc.

The Item data type holds fields that can apply to any of these, and leaves kind-specific details (like function args or enum variants) to the inner field.

Fields

id: Id

The unique identifier of this item. Can be used to find this item in various mappings.

crate_id: u32

This can be used as a key to the external_crates map of Crate to see which crate this item came from.

name: Option<String>

Some items such as impls don’t have names.

span: Option<Span>

The source location of this item (absent if it came from a macro expansion or inline assembly).

visibility: Visibility

By default all documented items are public, but you can tell rustdoc to output private items so this field is needed to differentiate.

docs: Option<String>

The full markdown docstring of this item. Absent if there is no documentation at all, Some(“”) if there is some documentation but it is empty (EG #[doc = ""]).

links: HashMap<String, Id>

This mapping resolves intra-doc links from the docstring to their IDs

attrs: Vec<String>

Stringified versions of the attributes on this item (e.g. "#[inline]")

deprecation: Option<Deprecation>

Information about the item’s deprecation, if present.

inner: ItemEnum

The type-specific fields describing this item.

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

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Item

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Item

fn eq(&self, other: &Item) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Item

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Item

impl StructuralPartialEq for Item
