Detailed Description

template<unsigned a0, unsigned a1, unsigned a2 = 0u, unsigned a3 = 0u, unsigned a4 = 0u, unsigned a5 = 0u, unsigned a6 = 0u, unsigned a7 = 0u, unsigned a8 = 0u>
struct senf::CheckINet6Network< a0, a1, a2, a3, a4, a5, a6, a7, a8 >

Check INet6Address against a fixed network prefix.

This helper allows to easily and efficiently check an INet6Address against an arbitrary but constant network prefix. It takes from 1 to 8 arguments for the network address and an additional last argument providing the prefix length. So

senf::CheckINet6Network< addr_1 , addr_2 , ... , prefix_len >

represents the network

addr_1 : addr_2 : ... ::/ prefix_len .

The class exposes a single static member match( addr ) which matches the INet6Address addr against the prefix:

if (senf::CheckINet6Network<0x2000u,0xDB8u,32u>::match(addr)) {
    // 'addr' is within in the 2001:db8::/32 documentation-only network
    ...
}

    The code generated by this call is highly optimized and probably as efficient as it can get.
