Functions ¶
func IsCIdentifier ¶
IsCIdentifier tests for a string that conforms the definition of an identifier in C. This checks the format, but not the length.
func IsDNS1123Label ¶
IsDNS1123Label tests for a string that conforms to the definition of a label in DNS (RFC 1123).
func IsDNS1123Subdomain ¶
IsDNS1123Subdomain tests for a string that conforms to the definition of a subdomain in DNS (RFC 1123).
func IsDNS952Label ¶
IsDNS952Label tests for a string that conforms to the definition of a label in DNS (RFC 952).
func IsQualifiedName ¶
func IsValidIPv4 ¶
IsValidIPv4 tests that the argument is a valid IPv4 address.
func IsValidLabelValue ¶
func IsValidPercent ¶
func IsValidPortName ¶
IsValidPortName check that the argument is valid syntax. It must be non empty and no more than 15 characters long It must contains at least one letter [a-z] and it must contains only [a-z0-9-]. Hypens ('-') cannot be leading or trailing character of the string and cannot be adjacent to other hyphens. Although RFC 6335 allows upper and lower case characters but case is ignored for comparison purposes: (HTTP and http denote the same service).
func IsValidPortNum ¶
IsValidPortNum tests that the argument is a valid, non-zero port number.
