Meta-data associated with an item Doc-comments are promoted to attributes that have is_sugared_doc = true

Fields

id: AttrId

path: Path

tokens: TokenStream

is_sugared_doc: bool

span: Span

Methods

impl Attribute

pub fn check_name(&self, name: &str) -> bool

pub fn name(&self) -> Option<Name>

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

pub fn meta_item_list(&self) -> Option<Vec<NestedMetaItem>>

pub fn is_word(&self) -> bool

pub fn span(&self) -> Span

pub fn is_meta_item_list(&self) -> bool

pub fn is_value_str(&self) -> bool

Indicates if the attribute is a Value String.

impl Attribute

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

Extract the MetaItem from inside this Attribute.

pub fn parse<'a, T, F>(&self, sess: &'a ParseSess, f: F) -> PResult<'a, T> where
    F: FnMut(&mut Parser<'a>) -> PResult<'a, T>, 

pub fn parse_list<'a, T, F>(
    &self,
    sess: &'a ParseSess,
    f: F
) -> PResult<'a, Vec<T>> where
    F: FnMut(&mut Parser<'a>) -> PResult<'a, T>, 

pub fn parse_meta<'a>(&self, sess: &'a ParseSess) -> PResult<'a, MetaItem>

pub fn with_desugared_doc<T, F>(&self, f: F) -> T where
    F: FnOnce(&Attribute) -> T, 

Convert self to a normal #[doc="foo"] comment, if it is a comment like /// or /** */. (Returns self unchanged for non-sugared doc attributes.)

Trait Implementations

impl ToTokens for Attribute

fn to_tokens(&self, _cx: &ExtCtxt) -> Vec<TokenTree>
