Struct MetaItemListParserContext

struct MetaItemListParserContext<'a> {
    inside_delimiters: Peekable<TokenStreamIter<'a>>,
    dcx: DiagCtxtHandle<'a>,
}

Fields

inside_delimiters: Peekable<TokenStreamIter<'a>>

dcx: DiagCtxtHandle<'a>

Implementations

impl<'a> MetaItemListParserContext<'a>

fn done(&mut self) -> bool

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

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

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

fn parse(self, span: Span) -> MetaItemListParser<'a>

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
