Expand description

Derives LowerHex trait implementation for newtype wrappers (i.e. tuple structs with a single non-zero sized element).

Accepts input in the following form:

($(where $($bound:tt)*)?)
$vis:vis struct $name:ident $(<$generics> $(where $where_clause)?)? (
    $(pub)? $t0:ty $(, $(pub)? $phantom:ty)* $(,)?
);
