Trait std::marker::MarkerTraitUnstable

pub trait MarkerTrait: PhantomFn<Self, ()> where Self: PhantomFn<Self, ()> { }

MarkerTrait is intended to be used as the supertrait for traits that don't have any methods but instead serve just to designate categories of types. An example would be the Send trait, which indicates types that are sendable: Send does not itself offer any methods, but instead is used to gate access to data.

FIXME. Better documentation needed here!
