# [−] [src] Macro syn::parenthesized

    macro_rules! parenthesized {
        ($content:ident in $cursor:expr) => { ... };
    }

Parse a set of parentheses and expose their content to subsequent parsers.

# Example

    use syn::{parenthesized, token, Ident, Result, Token, Type};
    use syn::parse::{Parse, ParseStream};
    use syn::punctuated::Punctuated;

    // Parse a simplified tuple struct syntax like:
    //
    //     struct S(A, B);
    struct TupleStruct {
        struct_token: Token![struct],
        ident: Ident,
        paren_token: token::Paren,
        fields: Punctuated<Type, Token![,]>,
        semi_token: Token![;],
    }

    impl Parse for TupleStruct {
        fn parse(input: ParseStream) -> Result<Self> {
            let content;
            Ok(TupleStruct {
                struct_token: input.parse()?,
                ident: input.parse()?,
                paren_token: parenthesized!(content in input),
                fields: content.parse_terminated(Type::parse)?,
                semi_token: input.parse()?,
            })
        }
    }
