[−][src]Struct syntax::ast::Attribute
Metadata associated with an item.
Doc-comments are promoted to attributes that have is_sugared_doc = true
.
Fields
id: AttrId
style: AttrStyle
path: Path
tokens: TokenStream
is_sugared_doc: bool
span: Span
Methods
impl Attribute
[src]
impl Attribute
pub fn check_name(&self, name: &str) -> bool | [src] |
pub fn name(&self) -> Name | [src] |
Returns the last segment of the name of this attribute.
e.g., foo
for #[foo]
, skip
for #[rustfmt::skip]
.
pub fn value_str(&self) -> Option<Symbol> | [src] |
pub fn meta_item_list(&self) -> Option<Vec<NestedMetaItem>> | [src] |
pub fn is_word(&self) -> bool | [src] |
pub fn span(&self) -> Span | [src] |
pub fn is_meta_item_list(&self) -> bool | [src] |
pub fn is_value_str(&self) -> bool | [src] |
Indicates if the attribute is a Value String.
impl Attribute
[src]
impl Attribute
pub fn meta(&self) -> Option<MetaItem> | [src] |
Extract the MetaItem from inside this Attribute.
pub fn parse<'a, T, F>(&self, sess: &'a ParseSess, f: F) -> PResult<'a, T> where | [src] |
pub fn parse_list<'a, T, F>( | [src] |
pub fn parse_meta<'a>(&self, sess: &'a ParseSess) -> PResult<'a, MetaItem> | [src] |
pub fn with_desugared_doc<T, F>(&self, f: F) -> T where | [src] |
Convert self to a normal #[doc="foo"] comment, if it is a
comment like ///
or /** */
. (Returns self unchanged for
non-sugared doc attributes.)
