package tag

import "golang.org/x/text/internal/tag"

Package tag contains functionality handling tags and related data.

Index ¶

• func Compare(a string, b []byte) int
• func FixCase(form string, b []byte) bool
• type Index
• func (s Index) Elem(x int) string
• func (s Index) Index(key []byte) int
• func (s Index) Next(key []byte, x int) int

Functions ¶

func Compare ¶

func Compare(a string, b []byte) int

Compare returns an integer comparing a and b lexicographically.

func FixCase ¶

func FixCase(form string, b []byte) bool

FixCase reformats b to the same pattern of cases as form. If returns false if string b is malformed.

Types ¶

type Index ¶

type Index string

An Index converts tags to a compact numeric value.

All elements are of size 4. Tags may be up to 4 bytes long. Excess bytes can be used to store additional information about the tag.

func (Index) Elem ¶

func (s Index) Elem(x int) string

Elem returns the element data at the given index.

func (Index) Index ¶

func (s Index) Index(key []byte) int

Index reports the index of the given key or -1 if it could not be found. Only the first len(key) bytes from the start of the 4-byte entries will be considered for the search and the first match in Index will be returned.

func (Index) Next ¶

func (s Index) Next(key []byte, x int) int

Next finds the next occurrence of key after index x, which must have been obtained from a call to Index using the same key. It returns x+1 or -1.
