	Binary8     = 252
	Binary20    = 253
	Binary32    = 254
	Nibble8     = 255
)

Type tokens used in the binary XML representation.

const (
	PackedMax     = 127
	SingleByteMax = 256
)

Other constants

const DictVersion = 3

DictVersion is the version number of the token lists above. It's sent when connecting to the websocket so the server knows which tokens are supported.

Variables ¶

var (
	SingleByteTokens = [...]string{ /* 236 elements not displayed */ }
	DoubleByteTokens = [...][]string{
		{ /* 256 elements not displayed */ },
		{ /* 256 elements not displayed */ },
		{ /* 256 elements not displayed */ },
		{ /* 256 elements not displayed */ },
	}
)

All the currently known string tokens.

Functions ¶

func GetDoubleToken ¶

func GetDoubleToken(index1, index2 int) (string, error)

GetDoubleToken gets the string value of the double-byte token at the given index.

func IndexOfDoubleByteToken ¶

func IndexOfDoubleByteToken(token string) (byte, byte, bool)

IndexOfDoubleByteToken gets the index of the double-byte token with the given string value. If there's no token with the given value, the third return value will be false.

func IndexOfSingleToken ¶

func IndexOfSingleToken(token string) (val byte, ok bool)

IndexOfSingleToken gets the index of the single-byte token with the given string value. If there's no token with the given value, the second return value will be false.
