Enum TemplateElement 

pub enum TemplateElement<O: SubstParseContext> {
    Ident(Ident, O::NotInConcat),
    LitStr(LitStr),
    Literal(Lit, (<O as SubstParseContext>::NotInPaste, <O as SubstParseContext>::NotInConcat)),

Variants

Ident(Ident, O::NotInConcat)

LitStr(LitStr)

Literal(Lit, (<O as SubstParseContext>::NotInPaste, <O as SubstParseContext>::NotInConcat))

Not used for syn::Lit::Str

Punct(Punct, (<O as SubstParseContext>::NotInPaste, <O as SubstParseContext>::NotInConcat))

Group

Fields

delim_span: Span

Sadly Group’s constructors let us only set both delimiters

delimiter: Delimiter

template: Template<O>

allow_tokens: (<O as SubstParseContext>::NotInPaste, <O as SubstParseContext>::NotInConcat)

Subst(Subst<O>)

Might contain SD::when

Repeat(RepeatedTemplate<O>)
