package atom

import "golang.org/x/net/html/atom"

Package atom provides integer codes (also known as atoms) for a fixed set of frequently occurring HTML strings: tag names and attribute keys such as "p" and "id".

Sharing an atom's name between all elements with the same tag can result in fewer string allocations when tokenizing and parsing HTML. Integer comparisons are also generally faster than string comparisons.

The value of an atom's particular code is not guaranteed to stay the same between versions of this package. Neither is any ordering guaranteed: whether atom.H1 < atom.H2 may also change. The codes are not guaranteed to be dense. The only guarantees are that e.g. looking up "div" will yield atom.Div, calling atom.Div.String will return "div", and atom.Div != 0.

Functions

func String

Types

type Atom
