Detailed Description

template<int Width, int Shift>
struct RAJA::BitMask< Width, Shift >

A bit-masking operator

Provides an operator that shifts and masks in input value to extract a contiguous set of bits.

result = (input >> Shift) & (Mask)

Where mask is (1<<Width)-1, or the number of bits defined by Width.
