Struct rustc_ap_rustc_session::Attribute[][src]

pub struct Attribute {
    pub kind: AttrKind,
    pub id: AttrId,
    pub style: AttrStyle,
    pub span: Span,

Metadata associated with an item.


kind: AttrKindid: AttrIdstyle: AttrStyle

Denotes if the attribute decorates the following construct (outer) or the construct this attribute is contained within (inner).

span: Span


impl Attribute[src]

pub fn has_name(&self, name: Symbol) -> bool[src]

pub fn ident(&self) -> Option<Ident>[src]

For a single-segment attribute, returns its name; otherwise, returns None.

pub fn name_or_empty(&self) -> Symbol[src]

pub fn value_str(&self) -> Option<Symbol>[src]

pub fn meta_item_list(&self) -> Option<Vec<NestedMetaItem, Global>>[src]

pub fn is_word(&self) -> bool[src]

pub fn is_meta_item_list(&self) -> bool[src]

pub fn is_value_str(&self) -> bool[src]

Indicates if the attribute is a ValueString.

pub fn name_value_literal_span(&self) -> Option<Span>[src]

This is used in case you want the value span instead of the whole attribute. Example:

#[doc(alias = "foo")]

In here, it'll return a span for "foo".

impl Attribute[src]

pub fn is_doc_comment(&self) -> bool[src]

pub fn doc_str(&self) -> Option<Symbol>[src]

pub fn get_normal_item(&self) -> &AttrItem[src]

pub fn unwrap_normal_item(self) -> AttrItem[src]

pub fn meta(&self) -> Option<MetaItem>[src]

Extracts the MetaItem from inside this Attribute.

pub fn tokens(&self) -> TokenStream[src]
