This is a simple library providing [`ParenthesizedC`] [ZST] that implements [`syn::parse::Parse`] and
thus, for example, can be used with [`syn::parse2`]\(\) for the purpose of parsing `(C)` [attribute tokens][attribute token] as in [#[repr(C)]][`#\[repr(C)\]`] [outer attribute].

# Example:


```rust
extern crate syn;
extern crate outer_attribute;
extern crate parenthesized_c;

use parenthesized_c::ParenthesizedC;
use outer_attribute::different_layout::OuterAttribute;

fn main() -> syn::Result<()> {
    let repr_c = syn::parse_str::<OuterAttribute>("#[repr(C)]")?;
    let repr_transpartent = syn::parse_str::<OuterAttribute>("#[repr(transparent)]")?;
    assert!(matches!(syn::parse2::<ParenthesizedC>(repr_c.tokens), Ok(_)));
    assert!(matches!(syn::parse2::<ParenthesizedC>(repr_transpartent.tokens), Err(_)));
    Ok(())
}
```
