Functions ¶
func ContainsAny ¶
ContainsAny reports whether any rune of chars is within s.
func ContainsFunc ¶
ContainsFunc reports whether any rune of s satisfies f.
func ContainsRune ¶
ContainsRune reports whether r is within s.
func Count ¶
Count counts the non-overlapping instances of substr in s. An empty substr counts as one more than the number of runes in s.
func FieldsFunc ¶
FieldsFunc splits s around runs of runes satisfying f.
func IndexRune ¶
IndexRune returns the index of the first instance of r in s, or -1. For utf8.RuneError it matches the first invalid byte or encoded U+FFFD.
func LastIndexAny ¶
LastIndexAny returns the index of the last rune of s that is in chars, or -1.
func LastIndexByte ¶
LastIndexByte returns the index of the last instance of c in s, or -1.
func LastIndexFunc ¶
LastIndexFunc returns the index of the last rune satisfying f, or -1.
func Map ¶
Map returns s with every rune mapped by mapping; runes mapped to a negative value are dropped. Invalid UTF-8 bytes are mapped as RuneError.
func Replace ¶
Replace returns s with the first n non-overlapping instances of old replaced by new; n < 0 replaces all. An empty old matches before every rune and at the end.
func ReplaceAll ¶
ReplaceAll replaces every non-overlapping instance of old with new.
func SplitAfter ¶
SplitAfter slices s after each instance of sep.
func SplitAfterN ¶
SplitAfterN slices s after each instance of sep into at most n substrings.
func ToValidUTF8 ¶
ToValidUTF8 replaces each run of invalid UTF-8 bytes with replacement.
func TrimLeftFunc ¶
TrimLeftFunc removes leading runes satisfying f.
func TrimPrefix ¶
TrimPrefix removes prefix from s if present.
func TrimRightFunc ¶
TrimRightFunc removes trailing runes satisfying f.
func TrimSuffix ¶
TrimSuffix removes suffix from s if present.
Types ¶
type Builder ¶
type Builder struct {
// contains filtered or unexported fields
}
Builder builds a string with appends.
type Reader ¶ added in v0.6.0
type Reader struct {
// contains filtered or unexported fields
}
Reader implements io.Reader, io.ReaderAt, io.Seeker, io.WriterTo, io.ByteScanner and io.RuneScanner over a string. The zero value reads nothing.
func (*Reader) ReadAt ¶ added in v0.6.0
ReadAt implements io.ReaderAt. It does not change the read position.
func (*Reader) UnreadByte ¶ added in v0.6.0
UnreadByte steps back one byte.
func (*Reader) UnreadRune ¶ added in v0.6.0
UnreadRune steps back over the rune returned by the previous ReadRune.
type Replacer ¶
type Replacer struct {
// contains filtered or unexported fields
}
Replacer replaces a list of strings with replacements.
func NewReplacer ¶
NewReplacer returns a Replacer from old, new string pairs. Replacements happen in target string order without overlapping; at the same position, earlier pairs win. It panics on an odd argument count.
