Struct enumflags2::ConstToken

source · 
pub struct ConstToken<T, N>(/* private fields */);
Expand description

Workaround for const fn limitations.

Some const fns in this crate will need an instance of this type for some type-level information usually provided by traits. For an example of usage, see not_c.
