Functions ¶
func Compare ¶
Compare returns an integer comparing two byte slices lexicographically. The result will be 0 if a==b, -1 if a < b, and +1 if a > b. A nil argument is equivalent to an empty slice.
func ContainsAny ¶
ContainsAny reports whether any of the UTF-8-encoded code points in chars are within b.
func ContainsByte ¶
ContainsByte reports whether the byte is contained in the slice b.
func ContainsRune ¶
ContainsRune reports whether the rune is contained in the UTF-8-encoded byte slice b.
func Count ¶
Count counts the number of non-overlapping instances of sep in s. If sep is an empty slice, Count returns 1 + the number of UTF-8-encoded code points in s.
func EndsWithByte ¶
EndsWithByte Tests if the byte slice bs ends with the specified suffix b.
func Equal ¶
Equal reports whether a and b are the same length and contain the same bytes. A nil argument is equivalent to an empty slice.
func EqualFold ¶
EqualFold reports whether s and t, interpreted as UTF-8 strings, are equal under Unicode case-folding, which is a more general form of case-insensitivity.
func Fields ¶
Fields interprets s as a sequence of UTF-8-encoded code points. It splits the slice s around each instance of one or more consecutive white space characters, as defined by unicode.IsSpace, returning a slice of subslices of s or an empty slice if s contains only white space.
func FieldsFunc ¶
FieldsFunc interprets s as a sequence of UTF-8-encoded code points. It splits the slice s at each run of code points c satisfying f(c) and returns a slice of subslices of s. If all code points in s satisfy f(c), or len(s) == 0, an empty slice is returned. FieldsFunc makes no guarantees about the order in which it calls f(c). If f does not return consistent results for a given c, FieldsFunc may crash.
func Index ¶
Index returns the index of the first instance of sep in s, or -1 if sep is not present in s.
func IndexAny ¶
IndexAny interprets s as a sequence of UTF-8-encoded Unicode code points. It returns the byte index of the first occurrence in s of any of the Unicode code points in chars. It returns -1 if chars is empty or if there is no code point in common.
func IndexByte ¶
IndexByte returns the index of the first instance of c in b, or -1 if c is not present in b.
func IndexFunc ¶
IndexFunc interprets s as a sequence of UTF-8-encoded code points. It returns the byte index in s of the first Unicode code point satisfying f(c), or -1 if none do.
func IndexRune ¶
IndexRune interprets s as a sequence of UTF-8-encoded code points. It returns the byte index of the first occurrence in s of the given rune. It returns -1 if rune is not present in s. If r is utf8.RuneError, it returns the first instance of any invalid UTF-8 byte sequence.
func Join ¶
Join concatenates the elements of s to create a new byte slice. The separator sep is placed between elements in the resulting slice.
func LastIndex ¶
LastIndex returns the index of the last instance of sep in s, or -1 if sep is not present in s.
func LastIndexAny ¶
LastIndexAny interprets s as a sequence of UTF-8-encoded Unicode code points. It returns the byte index of the last occurrence in s of any of the Unicode code points in chars. It returns -1 if chars is empty or if there is no code point in common.
func LastIndexByte ¶
LastIndexByte returns the index of the last instance of c in s, or -1 if c is not present in s.
func LastIndexFunc ¶
LastIndexFunc interprets s as a sequence of UTF-8-encoded code points. It returns the byte index in s of the last Unicode code point satisfying f(c), or -1 if none do.
func Map ¶
Map returns a copy of the byte slice s with all its characters modified according to the mapping function. If mapping returns a negative value, the character is dropped from the byte slice with no replacement. The characters in s and the output are interpreted as UTF-8-encoded code points.
func Repeat ¶
Repeat returns a new byte slice consisting of count copies of b.
It panics if count is negative or if the result of (len(b) * count) overflows.
func Replace ¶
Replace returns a copy of the slice s with the first n non-overlapping instances of old replaced by new. If old is empty, it matches at the beginning of the slice and after each UTF-8 sequence, yielding up to k+1 replacements for a k-rune slice. If n < 0, there is no limit on the number of replacements.
func ReplaceAll ¶
ReplaceAll returns a copy of the slice s with all non-overlapping instances of old replaced by new. If old is empty, it matches at the beginning of the slice and after each UTF-8 sequence, yielding up to k+1 replacements for a k-rune slice.
func Runes ¶
Runes interprets s as a sequence of UTF-8-encoded code points. It returns a slice of runes (Unicode code points) equivalent to s.
func Split ¶
Split slices s into all subslices separated by sep and returns a slice of the subslices between those separators. If sep is empty, Split splits after each UTF-8 sequence. It is equivalent to SplitN with a count of -1.
func SplitAfter ¶
SplitAfter slices s into all subslices after each instance of sep and returns a slice of those subslices. If sep is empty, SplitAfter splits after each UTF-8 sequence. It is equivalent to SplitAfterN with a count of -1.
func SplitAfterN ¶
SplitAfterN slices s into subslices after each instance of sep and returns a slice of those subslices. If sep is empty, SplitAfterN splits after each UTF-8 sequence. The count determines the number of subslices to return:
n > 0: at most n subslices; the last subslice will be the unsplit remainder. n == 0: the result is nil (zero subslices) n < 0: all subslices
func SplitN ¶
SplitN slices s into subslices separated by sep and returns a slice of the subslices between those separators. If sep is empty, SplitN splits after each UTF-8 sequence. The count determines the number of subslices to return:
n > 0: at most n subslices; the last subslice will be the unsplit remainder. n == 0: the result is nil (zero subslices) n < 0: all subslices
func StartsWith ¶
StartsWith Tests if the byte slice s starts with the specified prefix b.
func StartsWithByte ¶
StartsWithByte Tests if the byte slice s starts with the specified prefix b.
func Title ¶
Title treats s as UTF-8-encoded bytes and returns a copy with all Unicode letters that begin words mapped to their title case.
BUG(rsc): The rule Title uses for word boundaries does not handle Unicode punctuation properly.
func ToLower ¶
ToLower returns a copy of the byte slice s with all Unicode letters mapped to their lower case.
func ToLowerSpecial ¶
func ToLowerSpecial(c unicode.SpecialCase, s []byte) []byte
ToLowerSpecial treats s as UTF-8-encoded bytes and returns a copy with all the Unicode letters mapped to their lower case, giving priority to the special casing rules.
func ToTitle ¶
ToTitle treats s as UTF-8-encoded bytes and returns a copy with all the Unicode letters mapped to their title case.
func ToTitleSpecial ¶
func ToTitleSpecial(c unicode.SpecialCase, s []byte) []byte
ToTitleSpecial treats s as UTF-8-encoded bytes and returns a copy with all the Unicode letters mapped to their title case, giving priority to the special casing rules.
func ToUpper ¶
ToUpper returns a copy of the byte slice s with all Unicode letters mapped to their upper case.
func ToUpperSpecial ¶
func ToUpperSpecial(c unicode.SpecialCase, s []byte) []byte
ToUpperSpecial treats s as UTF-8-encoded bytes and returns a copy with all the Unicode letters mapped to their upper case, giving priority to the special casing rules.
func ToValidUTF8 ¶
ToValidUTF8 treats s as UTF-8-encoded bytes and returns a copy with each run of bytes representing invalid UTF-8 replaced with the bytes in replacement, which may be empty.
func Trim ¶
Trim returns a subslice of s by slicing off all leading and trailing UTF-8-encoded code points contained in cutset.
func TrimFunc ¶
TrimFunc returns a subslice of s by slicing off all leading and trailing UTF-8-encoded code points c that satisfy f(c).
func TrimLeft ¶
TrimLeft returns a subslice of s by slicing off all leading UTF-8-encoded code points contained in cutset.
func TrimLeftFunc ¶
TrimLeftFunc treats s as UTF-8-encoded bytes and returns a subslice of s by slicing off all leading UTF-8-encoded code points c that satisfy f(c).
func TrimPrefix ¶
TrimPrefix returns s without the provided leading prefix string. If s doesn't start with prefix, s is returned unchanged.
func TrimRight ¶
TrimRight returns a subslice of s by slicing off all trailing UTF-8-encoded code points that are contained in cutset.
func TrimRightFunc ¶
TrimRightFunc returns a subslice of s by slicing off all trailing UTF-8-encoded code points c that satisfy f(c).
func TrimSpace ¶
TrimSpace returns a subslice of s by slicing off all leading and trailing white space, as defined by Unicode.
func TrimSuffix ¶
TrimSuffix returns s without the provided trailing suffix string. If s doesn't end with suffix, s is returned unchanged.
