Create a byte encoding designed for static Go names. It is intended to be a compact representation of a name and optional tag data that can be turned into a Go string without allocating, and describes whether or not it is exported without unicode table. The encoding is described in reflect/type.go: // The first byte is a bit field containing: // // 1<<0 the name is exported // 1<<1 tag data follows the name // 1<<2 pkgPath *string follow the name and tag // // The next two bytes are the data length: // // l := uint16(data[1])<<8 | uint16(data[2]) // // Bytes [3:3+l] are the string data. // // If tag data follows then bytes 3+l and 3+l+1 are the tag length, // with the data following. // // If the import path follows, then ptrSize bytes at the end of // the data form a *string. The import path is only set for concrete // methods that are defined in a different package than their type. Shrinks binary sizes: cmd/go: 164KB (1.6%) jujud: 1.0MB (1.5%) For #6853.
