Package-Level Type Names (only one)

/* sort by: alphabet | popularity */

type AcceptRange (struct) AcceptRange gives the range of valid values for the second byte in a UTF-8 sequence for any value for First that is not ASCII or FirstInvalid. Fields (total 2) Hi uint8 // highest value for second byte. Lo uint8 // lowest value for second byte.

Package-Level Variables (total 2)

var AcceptRanges [5]AcceptRange AcceptRanges is a slice of AcceptRange values. For a given byte sequence b AcceptRanges[First[b[0]]>>AcceptShift] will give the value of AcceptRange for the multi-byte UTF-8 sequence starting at b[0].

var First [256]uint8 First is information about the first byte in a UTF-8 sequence.

Package-Level Constants (total 6)

const AcceptShift = 4 AcceptShift is the right-shift count for the first byte info byte to get the index into the AcceptRanges table. See AcceptRanges.

const ASCII = 240 ASCII identifies a UTF-8 byte as ASCII.

const FirstInvalid = 241 FirstInvalid indicates a byte is invalid as a first byte of a UTF-8 sequence.

const HiCB = 191 // 1011 1111 The default lowest and highest continuation byte.

const LoCB = 128 // 1000 0000 The default lowest and highest continuation byte.

const SizeMask = 7 SizeMask is a mask for the size bits. Use use x&SizeMask to get the size.
