Functions

func BytesToStringUnsafe

func BytesToStringUnsafe(b []byte) string

BytesToStringUnsafe converts bytes to string.

func CheckNumRange

func CheckNumRange[K constraints.Integer | constraints.Float](v, min, max K) bool

func ClosedChan

func ClosedChan(c chan struct{}) bool

ClosedChan returns true if c is closed. c must not use for sending data and must be used in close() only. If ClosedChan receives something from c, it panics.

func GenerateCertificate

func GenerateCertificate(dnsName string) (cert tls.Certificate, err error)

GenerateCertificate generates an ecdsa certificate with given dnsName. This should only use in test.

func GetAddrFromAddr

func GetAddrFromAddr(addr net.Addr) netip.Addr

GetAddrFromAddr returns netip.Addr from net.Addr. See also: GetIPFromAddr.

func GetIPFromAddr

func GetIPFromAddr(addr net.Addr) (ip net.IP)

GetIPFromAddr returns a net.IP from the given net.Addr. addr can be *net.TCPAddr, *net.UDPAddr, *net.IPNet, *net.IPAddr Will return nil otherwise.

func LoadCertPool

func LoadCertPool(certs []string) (*x509.CertPool, error)

LoadCertPool reads and loads certificates in certs.

func ParseNameOrNum

func ParseNameOrNum[T constraints.Integer](s string, m map[string]T) (T, bool)

func RemoveComment

func RemoveComment(s, symbol string) string

RemoveComment removes comment after "symbol".

func SetDefaultNum

func SetDefaultNum[K constraints.Integer | constraints.Float](p *K, d K)

func SetDefaultString

func SetDefaultString(p *string, d string)

func SetDefaultUnsignNum

func SetDefaultUnsignNum[K constraints.Integer | constraints.Float](p *K, d K)

func SplitLineReg

func SplitLineReg(s string) []string

SplitLineReg extracts words from s by using regexp "\S+".

func SplitSchemeAndHost

func SplitSchemeAndHost(addr string) (protocol, host string)

SplitSchemeAndHost splits addr to protocol and host.

func SplitString2

func SplitString2(s, symbol string) (s1 string, s2 string, ok bool)

SplitString2 split s to two parts by given symbol

func WeakDecode

func WeakDecode(in any, output any) error

WeakDecode decodes args from config to output.

Types

type Errors

type Errors struct {
	sync.RWMutex
	// contains filtered or unexported fields
}

func (*Errors) Append

func (c *Errors) Append(err error)

func (*Errors) Error

func (c *Errors) Error() string

func (*Errors) Len

func (c *Errors) Len() int
