Implementations§

Source§

impl Subst<BooleanContext>

Source

pub fn eval_bool<'c>(&self, gctx: GeneralContext<'c>) -> Result<bool>

Source§

impl<O: SubstParseContext> Subst<O>

Source

pub fn parse_entire(input: ParseStream<'_>) -> Result<Self>

Parses everything including a $ (which we insist on)

Source

fn parse_after_dollar( la: Lookahead1<'_>, input: ParseStream<'_>, _deescaped: OrigDollarHandled, ) -> Result<Self>

Parses everything after the $, possibly including a pair of { }

You must have called deescape_orig_dollar, and handled the $$ case.
