Documentation

Overview

Package ipbits contains utilities for manipulating netip.Addr values as numbers or bitfields.

Index

• func Add(ip netip.Addr, x uint64, shift uint) netip.Addr
• func Field(ip netip.Addr, u, v uint) uint64

Functions

func Add

func Add(ip netip.Addr, x uint64, shift uint) netip.Addr

Add returns ip + (x << shift).

func Field

func Field(ip netip.Addr, u, v uint) uint64

Field returns the value of the bitfield [u, v] in ip as an integer, where bit 0 is the most-significant bit of ip.

The result is undefined if u > v, if v-u > 64, or if u or v is larger than ip.BitLen().
