Documentation

Overview

Package runes provides a small subset of functions for rune slices that are found in the strings and bytes standard packages. For rendering and other logic, it is best to keep raw data in runes, and not having to convert back and forth to bytes or strings is more efficient.

These are largely copied from the strings or bytes packages.

Index

• func EqualFold(s, t []rune) bool
• func Index(txt, find []rune) int
• func IndexFold(txt, find []rune) int
• func Repeat(r []rune, count int) []rune
• func SetFromBytes(rs []rune, s []byte) []rune

Functions

func EqualFold

func EqualFold(s, t []rune) bool

EqualFold reports whether s and t are equal under Unicode case-folding. copied from strings.EqualFold

func Index

func Index(txt, find []rune) int

Index returns the index of given rune string in the text, returning -1 if not found.

func IndexFold

func IndexFold(txt, find []rune) int

IndexFold returns the index of given rune string in the text, using case folding (i.e., case insensitive matching). Returns -1 if not found.

func Repeat

func Repeat(r []rune, count int) []rune

Repeat returns a new rune slice consisting of count copies of b.

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

func SetFromBytes

func SetFromBytes(rs []rune, s []byte) []rune

SetFromBytes sets slice of runes from given slice of bytes, using efficient memory reallocation of existing slice. returns potentially modified slice: use assign to update.
