# Macro synom::separated_nonempty_list [−] [src]

    macro_rules! separated_nonempty_list {
        ($i:expr, $sep:ident!( $($args:tt)* ), $submac:ident!( $($args2:tt)* )) => { ... };
        ($i:expr, $submac:ident!( $($args:tt)* ), $g:expr) => { ... };
        ($i:expr, $f:expr, $submac:ident!( $($args:tt)* )) => { ... };
        ($i:expr, $f:expr, $g:expr) => { ... };
    }

One or more values separated by some separator. Does not allow a trailing separator.

- Syntax: `separated_nonempty_list!(SEPARATOR, THING)`
- Output: `Vec<THING>`

You may also be looking for:

- `separated_list!` - one or more values
- `terminated_list!` - zero or more, allows trailing separator
- `many0!` - zero or more, no separator

    extern crate syn;

    use syn::Ty;
    use syn::parse::ty;

    // One or more Rust types separated by commas.
    named!(comma_separated_types -> Vec<Ty>,
        separated_nonempty_list!(punct!(","), ty)
    );

    fn main() {
        let input = "&str, Map<K, V>, String";

        let parsed = comma_separated_types(input).expect("comma-separated types");

        assert_eq!(parsed.len(), 3);
        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`)
