Functions

func SelectQValue

func SelectQValue(header string, allowed []string) string

SelectQValue selects and returns the best value from the allowed set given a header with optional quality values, as you would get for an Accept or Accept-Encoding header. The *first* item in allowed is preferred if there is a tie. If nothing matches, returns an empty string.

func SelectQValueFast

func SelectQValueFast(header string, allowed []string) string

SelectQValueFast is a faster version of SelectQValue that does not need any dynamic memory allocations.
