Detailed Description

template<typename D1, typename D2 = D1, typename D3 = D2, enum Backend implementation = config::default_backend>
class grb::operators::equal_first< D1, D2, D3, implementation >

Compares std::pair inputs taking the first entry in every pair as the comparison key, and returns true or false accordingly.

The input domains must both be std::pair.

Note

If the output type is not Boolean, the output is cast from Boolean to the output domain.

The output domain must hence be castable from bool.
