Struct Or 

Source 
pub struct Or<Left, Right> { /* private fields */ }
Expand description

A specification that requires either of two specifications to be satisfied.

Construct this type with Specification::or. Its operands remain concrete types, so the composition does not allocate or use dynamic dispatch.
