Functions

func EscapeBytes

func EscapeBytes(value string) string

EscapeBytes adds a backslash to \, ], " characters.

func InBetween

func InBetween(val, min, max int) bool

InBetween tells whether value is into [min, max] range.

func RemoveBytes

func RemoveBytes(data []byte, positions []int, offset int) []byte

RemoveBytes removes byte at given positions from data byte slice, starting from the given offset.

func UnsafeUTF8DecimalCodePointsToInt

func UnsafeUTF8DecimalCodePointsToInt(chars []uint8) int

UnsafeUTF8DecimalCodePointsToInt converts a slice containing a series of UTF-8 decimal code points into their integer rapresentation.

It assumes input code points are in the range 48-57. Returns a pointer since an empty slice is equal to nil and not to the zero value of the codomain (ie., `int`).

func ValidPriority

func ValidPriority(priority uint8) bool

ValidPriority checks whether the given value is in the priority range [0, 191].

func ValidVersion

func ValidVersion(version uint16) bool

ValidVersion checks whether the given value is in the version range [1, 999].
