# Macro synom::delimited [−] [src]

    macro_rules! delimited {
        ($i:expr, $submac:ident!( $($args:tt)* ), $($rest:tt)+) => { ... };
        ($i:expr, $f:expr, $($rest:tt)+) => { ... };
    }

Value surrounded by a pair of delimiters.

- Syntax: `delimited!(OPEN, THING, CLOSE)`
- Output: `THING`

    extern crate syn;
    #[macro_use] extern crate synom;

    use syn::Expr;
    use syn::parse::expr;

    // An expression surrounded by [[ ... ]].
    named!(double_bracket_expr -> Expr,
        delimited!(punct!("[["), expr, punct!("]]"))
    );

    fn main() {
        let input = "[[ 1 + 1 ]]";

        let parsed = double_bracket_expr(input).expect("double bracket expr");

        println!("{:?}", parsed);
    }

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
