Methods

impl Attribute

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

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

Returns true if the attribute's path matches the argument. If it matches, then the attribute is marked as used.

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

pub fn is_meta_item_list(&self) -> bool

pub fn is_value_str(&self) -> bool

Indicates if the attribute is a ValueString.

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.
