Methods
impl NestedMetaItem[src]
impl NestedMetaItempub fn meta_item(&self) -> Option<&MetaItem>[src]
pub fn meta_item(&self) -> Option<&MetaItem>Returns the MetaItem if self is a NestedMetaItemKind::MetaItem.
pub fn literal(&self) -> Option<&Lit>[src]
pub fn literal(&self) -> Option<&Lit>Returns the Lit if self is a NestedMetaItemKind::Literal.
pub fn span(&self) -> Span[src]
pub fn span(&self) -> SpanReturns the Span for self.
pub fn check_name(&self, name: &str) -> bool[src]
pub fn check_name(&self, name: &str) -> boolReturns true if this list item is a MetaItem with a name of name.
pub fn name(&self) -> Option<Name>[src]
pub fn name(&self) -> Option<Name>Returns the name of the meta item, e.g. foo in #[foo],
#[foo="bar"] and #[foo(bar)], if self is a MetaItem
pub fn value_str(&self) -> Option<Symbol>[src]
pub fn value_str(&self) -> Option<Symbol>Gets the string value if self is a MetaItem and the MetaItem is a MetaItemKind::NameValue variant containing a string, otherwise None.
pub fn name_value_literal(&self) -> Option<(Name, &Lit)>[src]
pub fn name_value_literal(&self) -> Option<(Name, &Lit)>Returns a name and single literal value tuple of the MetaItem.
pub fn word(&self) -> Option<&MetaItem>[src]
