Functions ¶
func FirstLabel ¶
FirstLabel returns the first DNS label of hostname.
func HasSuffix ¶
HasSuffix reports whether the provided name ends with the component(s) in suffix, ignoring any trailing or leading dots.
If suffix is the empty string, HasSuffix always reports false.
func NumLabels ¶
NumLabels returns the number of DNS labels in hostname. If hostname is empty or the top-level name ".", returns 0.
func SanitizeHostname ¶
SanitizeHostname turns hostname into a valid name label according to RFC 1035.
func SanitizeLabel ¶
SanitizeLabel takes a string intended to be a DNS name label and turns it into a valid name label according to RFC 1035.
func TrimCommonSuffixes ¶
TrimCommonSuffixes returns hostname with some common suffixes removed.
func TrimSuffix ¶
TrimSuffix trims any trailing dots from a name and removes the suffix ending if present. The name will never be returned with a trailing dot, even after trimming.
Types ¶
