Functions ¶

func MustParse4 ¶

func MustParse4(addr string) tcpip.Address

MustParse4 parses an IPv4 string (e.g. "192.168.1.1") into a tcpip.Address. Passing an IPv4-mapped IPv6 address will yield only the 4 IPv4 bytes.

func MustParse6 ¶

func MustParse6(addr string) tcpip.Address

MustParse6 parses an IPv6 string (e.g. "fe80::1") into a tcpip.Address. Passing an IPv4 address will yield an IPv4-mapped IPv6 address.

func MustParseLink ¶

func MustParseLink(addr string) tcpip.LinkAddress

MustParseLink parses a Link string into a tcpip.LinkAddress, panicking on error.

The string must be in the format aa:bb:cc:dd:ee:ff or aa-bb-cc-dd-ee-ff.

func MustParseSubnet4 ¶

func MustParseSubnet4(subnet string) tcpip.Subnet

MustParseSubnet4 parses an IPv4 subnet string (e.g. "192.168.1.0/24") into a tcpip.Subnet.

func ValidateMultiCounterStats ¶

func ValidateMultiCounterStats(multi reflect.Value, counters []reflect.Value, options ValidateMultiCounterStatsOptions) error

ValidateMultiCounterStats verifies that every counter stored in multi is correctly tracking its counterpart in the given counters.

Types ¶

type ValidateMultiCounterStatsOptions ¶

type ValidateMultiCounterStatsOptions struct {
	ExpectMultiCounterStat            bool
	ExpectMultiIntegralStatCounterMap bool
}

ValidateMultiCounterStatsOptions holds options used when validating multi counter stat structs.
