MouseX::NativeTraits::Counter - Helper trait for counter attributes

       This module provides a simple counter attribute, which can be incremented and decremented.

       If your attribute definition does not include any of is, isa, default or handles but does use the
       "Counter" trait, then this module applies defaults as in the "SYNOPSIS" above. This allows for a very
       basic counter definition:

         has 'foo' => (traits => ['Counter']);
         $obj->inc_foo;

       MouseX::NativeTraits::Counter - Helper trait for counter attributes

       These methods are implemented in MouseX::NativeTraits::MethodProvider::Counter. It is important to note
       that all those methods do in place modification of the value stored in the attribute.

       set($value)
           Set the counter to the specified value.

       inc Increments  the  value  stored  in this slot by 1. Providing an argument will cause the counter to be
           increased by specified amount.

       dec Decrements the value stored in this slot by 1. Providing an argument will cause  the  counter  to  be
           increased by specified amount.

       reset
           Resets the value stored in this slot to it's default value.
