Functions

func Append

func Append[T ~[]S, S E](arr T, v S) (T, int)

Append appends the element v to the end of Array[S] s.

func Contains

func Contains[T ~[]S, S E](s, sub T) bool

Contains reports whether substr is within s.

func ContainsArray

func ContainsArray[T ~[]S, S E](s T, e S) bool

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

func ContainsRune

func ContainsRune(s []rune, r rune) bool

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

func Count

func Count[T ~[]S, S E](s, sub T) int

Count counts the number of non-overlapping instances of substr in s. If substr is an empty Array, Count returns 1 + the number of Unicode code points in s.

func CountArray

func CountArray[T ~[]S, S E](ss T, s S) int

CountArray counts the number of non-overlapping instances of c in s.

func Cut

func Cut[T ~[]S, S E](s, sep T) (before, after T, found bool)

Cut slices s around the first instance of sep, returning the text before and after sep. The found result reports whether sep appears in s. If sep does not appear in s, cut returns s, "", false.

func Equal

func Equal[T ~[]S, S E](a, b T) bool

Equal reports whether a and b are the same length and contain the same runes. A nil argument is equivalent to an empty slice.

func EqualFoldRune

func EqualFoldRune(s, t []rune) bool

EqualFoldRune reports whether s and t, interpreted as UTF-8 []runes, are equal under simple Unicode case-folding, which is a more general form of case-insensitivity.

func Fields

func Fields[T ~[]S, S interface{ ~byte | ~rune }](s T) []T

Fields splits the Array s around each instance of one or more consecutive white space characters, as defined by unicode.IsSpace, returning a slice of subArrays of s or an empty slice if s contains only white space.

func FieldsFunc

func FieldsFunc[T ~[]S, S E](s T, f func(S) bool) []T

FieldsFunc splits the Array s at each run of Unicode code points c satisfying f(c) and returns an array of slices of s. If all code points in s satisfy f(c) or the Array is empty, an empty slice is returned.

FieldsFunc makes no guarantees about the order in which it calls f(c) and assumes that f always returns the same value for a given c.

func HasPrefix

func HasPrefix[T ~[]S, S E](s, prefix T) bool

HasPrefix tests whether the Array[S] s begins with prefix.

func HasSuffix

func HasSuffix[T ~[]S, S E](s, suffix T) bool

HasSuffix tests whether the Array[S] s ends with suffix.

func Index[T ~[]S, S E](s, sep T) int

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

func IndexArray

func IndexArray[T ~[]S, S E](s T, r S) int

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

func IndexByteRune

func IndexByteRune(s []rune, c byte) int

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

func IndexFunc

func IndexFunc[T ~[]S, S E](s T, f func(S) bool) int

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

func IndexRune

func IndexRune(s []rune, r rune) int

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

func IsSpace

func IsSpace[S interface{ ~byte | ~rune }](r S) bool

func Join

func Join[T ~[]S, S E](s []T, sep T) T

Join concatenates the elements of its first argument to create a single Array[S]. The separator Array[S] sep is placed between elements in the resulting Array[S].

func LastIndex

func LastIndex[T ~[]S, S E](s, sep T) int

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

func LastIndexArray

func LastIndexArray[T ~[]S, S E](s T, c S) int

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

func LastIndexFunc

func LastIndexFunc[T ~[]S, S E](s T, f func(S) bool) int

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

func MapRune

func MapRune(mapping func(rune) rune, s []rune) []rune

MapRune returns a copy of the []rune s with all its characters modified according to the mapping function. If mapping returns a negative value, the character is dropped from the []rune with no replacement.

func Read

func Read[T ~[]S, S E](arr T, offset int, limit int) T

Read returns a slice of the Array[S] s beginning at offset and length limit. If offset or limit is negative, it is treated as if it were zero.

func Repeat

func Repeat[T ~[]S, S E](b T, count int) T

Repeat returns a new Array[S] consisting of count copies of the Array[S] s.

It panics if count is negative or if the result of (len(s) * count) overflows.

func Replace

func Replace[T ~[]S, S E](s, old, new T, n int) T

Replace returns a copy of the Array s with the first n non-overlapping instances of old replaced by new. If old is empty, it matches at the beginning of the Array and after each UTF-8 sequence, yielding up to k+1 replacements for a k-rune Array. If n < 0, there is no limit on the number of replacements.

func ReplaceAll

func ReplaceAll[T ~[]S, S E](s, old, new T) T

ReplaceAll returns a copy of the Array s with all non-overlapping instances of old replaced by new. If old is empty, it matches at the beginning of the Array and after each UTF-8 sequence, yielding up to k+1 replacements for a k-rune Array.

func Split

func Split[T ~[]S, S E](s, sep T) []T

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

If s does not contain sep and sep is not empty, Split returns a slice of length 1 whose only element is s.

If sep is empty, Split splits after each UTF-8 sequence. If both s and sep are empty, Split returns an empty slice.

It is equivalent to SplitN with a count of -1.

To split around the first instance of a separator, see Cut.

func SplitAfter

func SplitAfter[T ~[]S, S E](s, sep T) []T

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

If s does not contain sep and sep is not empty, SplitAfter returns a slice of length 1 whose only element is s.

If sep is empty, SplitAfter splits after each UTF-8 sequence. If both s and sep are empty, SplitAfter returns an empty slice.

It is equivalent to SplitAfterN with a count of -1.

func SplitAfterN

func SplitAfterN[T ~[]S, S E](s, sep T, n int) []T

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

The count determines the number of sub arrays to return:

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

Edge cases for s and sep (for example, empty Arrays) are handled as described in the documentation for SplitAfter.

func SplitN

func SplitN[T ~[]S, S E](s, sep T, n int) []T

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

The count determines the number of sub arrays to return:

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

Edge cases for s and sep (for example, empty Arrays) are handled as described in the documentation for Split.

To split around the first instance of a separator, see Cut.
