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: FxHashMap<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: FxHashMap<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

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.
