Implementations§

Source§

impl<'a, 'sess> MetaItemListParserContext<'a, 'sess>

Source

fn done(&mut self) -> bool

Source

fn next_path(&mut self) -> Option<AttrPath>

Source

fn value(&mut self) -> Option<MetaItemLit>

Source

fn next(&mut self) -> Option<MetaItemOrLitParser<'a>>

parses one element on the inside of a list attribute like #[my_attr( <insides> )]

parses a path followed be either:

  1. nothing (a word attr)
  2. a parenthesized list
  3. an equals sign and a literal (name-value)

Can also parse just a literal. This is for cases like as #[my_attr("literal")] where no path is given before the literal

Some exceptions too for interpolated attributes which are already pre-processed
