Compare returns an integer comparing two strings lexicographically.

Contains reports whether substr is within s.

ContainsAny reports whether any Unicode code points in chars are within s.

ContainsRune reports whether the Unicode code point r is within s.

Count counts the number of non-overlapping instances of sep in s.

EqualFold reports whether s and t, interpreted as UTF-8 strings, are equal under Unicode case-folding.

Fields splits the string s around each instance of one or more consecutive white space characters, as defined by unicode.IsSpace, returning an array of substrings of s or an empty list if s contains only white space.

FieldsFunc splits the string s at each run of Unicode code points c satisfying f(c) and returns an array of slices of s.

HasPrefix tests whether the string s begins with prefix.

HasSuffix tests whether the string s ends with suffix.

Index returns the index of the first instance of sep in s, or -1 if sep is not present in s.

IndexAny returns the index of the first instance of any Unicode code point from chars in s, or -1 if no Unicode code point from chars is present in s.

IndexByte returns the index of the first instance of c in s, or -1 if c is not present in s.

IndexFunc returns the index into s of the first Unicode code point satisfying f(c), or -1 if none do.

IndexRune returns the index of the first instance of the Unicode code point r, or -1 if rune is not present in s.

Join concatenates the elements of a to create a single string.

LastIndex returns the index of the last instance of sep in s, or -1 if sep is not present in s.

LastIndexAny returns the index of the last instance of any Unicode code point from chars in s, or -1 if no Unicode code point from chars is present in s.

LastIndexByte returns the index of the last instance of c in s, or -1 if c is not present in s.

LastIndexFunc returns the index into s of the last Unicode code point satisfying f(c), or -1 if none do.

Map returns a copy of the string s with all its characters modified according to the mapping function.

NewReader returns a new Reader reading from s.

NewReplacer returns a new Replacer from a list of old, new string pairs.

Repeat returns a new string consisting of count copies of the string s.

Replace returns a copy of the string s with the first n non-overlapping instances of old replaced by new.

Split slices s into all substrings separated by sep and returns a slice of the substrings between those separators.

SplitAfter slices s into all substrings after each instance of sep and returns a slice of those substrings.

SplitAfterN slices s into substrings after each instance of sep and returns a slice of those substrings.

SplitN slices s into substrings separated by sep and returns a slice of the substrings between those separators.

Title returns a copy of the string s with all Unicode letters that begin words mapped to their title case.

ToLower returns a copy of the string s with all Unicode letters mapped to their lower case.

ToLowerSpecial returns a copy of the string s with all Unicode letters mapped to their lower case, giving priority to the special casing rules.

ToTitle returns a copy of the string s with all Unicode letters mapped to their title case.

ToTitleSpecial returns a copy of the string s with all Unicode letters mapped to their title case, giving priority to the special casing rules.

ToUpper returns a copy of the string s with all Unicode letters mapped to their upper case.

ToUpperSpecial returns a copy of the string s with all Unicode letters mapped to their upper case, giving priority to the special casing rules.

Trim returns a slice of the string s with all leading and trailing Unicode code points contained in cutset removed.

TrimFunc returns a slice of the string s with all leading and trailing Unicode code points c satisfying f(c) removed.

TrimLeft returns a slice of the string s with all leading Unicode code points contained in cutset removed.

TrimLeftFunc returns a slice of the string s with all leading Unicode code points c satisfying f(c) removed.

TrimPrefix returns s without the provided leading prefix string.

TrimRight returns a slice of the string s, with all trailing Unicode code points contained in cutset removed.

TrimRightFunc returns a slice of the string s with all trailing Unicode code points c satisfying f(c) removed.

TrimSpace returns a slice of the string s, with all leading and trailing white space removed, as defined by Unicode.

TrimSuffix returns s without the provided trailing suffix string.

A Reader implements the io.Reader, io.ReaderAt, io.Seeker, io.WriterTo, io.ByteScanner, and io.RuneScanner interfaces by reading from a string.

Replacer replaces a list of strings with replacements.
