Understanding Runes in Go: A Comprehensive Guide
In Go, a rune
is a data type that represents a single Unicode code point. It is essentially an alias for the int32
type, allowing it to store any character from the Unicode character set, which includes a vast array of characters from different languages and symbols. This is particularly useful because Go uses UTF-8 encoding, where characters can take up to four bytes.
You can convert a string to a slice of runes using the []rune
conversion. This is useful when you need to manipulate individual characters in a string
s := "Hello"
r := []rune(s) // Converts string to a slice of runes
Runes in Go are a data type representing single Unicode code points, essentially aliases for the int32 type. They accommodate characters from the Unicode set, supporting multi-byte UTF-8 encoding. Converting a string to a slice of runes using the []rune conversion allows for individual character manipulation.
