Functions ¶

func AppendSplitN ¶

func AppendSplitN(dst []string, s, sep string, n int) []string

AppendSplitN is like strings.SplitN but appends to and returns dst. Unlike strings.SplitN, an empty separator is not supported. The count n determines the number of substrings to return:

n > 0: at most n substrings; the last substring will be the unsplit remainder.
n == 0: the result is nil (zero substrings)
n < 0: all substrings

func ContainsFold ¶

func ContainsFold(s, substr string) bool

ContainsFold is like strings.Contains but uses Unicode case-folding.

func HasPrefixFold ¶

func HasPrefixFold(s, prefix string) bool

HasPrefixFold is like strings.HasPrefix but uses Unicode case-folding, matching case insensitively.

func HasSuffixFold ¶

func HasSuffixFold(s, suffix string) bool

HasSuffixFold is like strings.HasSuffix but uses Unicode case-folding, matching case insensitively.

func IsPlausibleJSON ¶

func IsPlausibleJSON(s string) bool

IsPlausibleJSON reports whether s likely contains a JSON object, without actually parsing it. It's meant to be a light heuristic.

func ParseUintBytes ¶

func ParseUintBytes(s []byte, base int, bitSize int) (n uint64, err error)

ParseUintBytes is like strconv.ParseUint, but using a []byte.

func RegisterCommonString ¶

func RegisterCommonString(s ...string)

RegisterCommonString adds common strings to the interned string table. This should be called during init from the main goroutine, not later at runtime.

func StringFromBytes ¶

func StringFromBytes(v []byte) string

StringFromBytes returns string(v), minimizing copies for common values of v as previously registered with RegisterCommonString.
