BitmaskType
C++ concepts: BitmaskType
Defines a type that can be used to represent a set of constant values or any combination of those values. This trait is typically implemented by integer types, std::bitset
, or enumerations (scoped and unscoped) with additional operator overloads.
Requirements
The bitmask type supports a finite number of bitmask elements, which are distinct non-zero values of the bitmask type, such that, for any pair Ci and Cj, Ci & Ci != 0
and Ci & Cj == 0
. In addition, the value 0
is used to represent an empty bitmask, with no values set.
