Implementations

impl Attribute

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

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

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

pub fn name_or_empty(&self) -> Symbol

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

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

pub fn is_word(&self) -> bool

impl Attribute

pub fn is_doc_comment(&self) -> bool

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

pub fn get_normal_item(&self) -> &AttrItem

pub fn unwrap_normal_item(self) -> AttrItem

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

Extracts the MetaItem from inside this Attribute.

pub fn tokens(&self) -> AttrAnnotatedTokenStream

Trait Implementations

impl AstLike for Attribute

const SUPPORTS_CUSTOM_INNER_ATTRS: bool

This is true if this AstLike might support ‘custom’ (proc-macro) inner attributes. Attributes like #![cfg] and #![cfg_attr] are not considered ‘custom’ attributes

fn attrs(&self) -> &[Attribute]

fn visit_attrs(&mut self, _f: impl FnOnce(&mut Vec<Attribute>))

fn tokens_mut(&mut self) -> Option<&mut Option<LazyTokenStream>>

impl Clone for Attribute

fn clone(&self) -> Attribute

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Attribute

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

Formats the value using the given formatter.

impl<__D: Decoder> Decodable<__D> for Attribute

fn decode(__decoder: &mut __D) -> Result<Self, <__D as Decoder>::Error>

impl<__E: Encoder> Encodable<__E> for Attribute

fn encode(&self, __encoder: &mut __E) -> Result<(), <__E as Encoder>::Error>

impl<AstCtx: HashStableContext> HashStable<AstCtx> for Attribute

fn hash_stable(&self, hcx: &mut AstCtx, hasher: &mut StableHasher)
