-// This file contains definitions for interpreting the trie value of the idna
-// trie generated by "go run gen*.go". It is shared by both the generator
-// program and the resultant package. Sharing is achieved by the generator
-// copying gen_trieval.go to trieval.go and changing what's above this comment.

-// info holds information from the IDNA mapping table for a single rune. It is
-// the value returned by a trie lookup. In most cases, all information fits in
-// a 16-bit value. For mappings, this value may contain an index into a slice
-// with the mapped string. Such mappings can consist of the actual mapped value
-// or an XOR pattern to be applied to the bytes of the UTF8 encoding of the
-// input rune. This technique is used by the cases packages and reduces the
-// table size significantly.
-//
-// The per-rune values have the following format:
-//
-// if mapped {
-// if inlinedXOR {
-// 15..13 inline XOR marker
-// 12..11 unused
-// 10..3 inline XOR mask
-// } else {
-// 15..3 index into xor or mapping table
-// }
-// } else {
-// 15..14 unused
-// 13 mayNeedNorm
-// 12..11 attributes
-// 10..8 joining type
-// 7..3 category type
-// }
-// 2 use xor pattern
-// 1..0 mapped category
-//
-// See the definitions below for a more detailed description of the various
-// bits.
