// SimpleHandle is a Handle for a very simple encoding format.

//
|
|
// simple is a simplistic codec similar to binc, but not as compact.
|
|
// - Encoding of a value is always preceded by the descriptor byte (bd)
|
|
// - True, false, nil are encoded fully in 1 byte (the descriptor)
|
|
// - Integers (intXXX, uintXXX) are encoded in 1, 2, 4 or 8 bytes (plus a descriptor byte).
|
|
// There are positive (uintXXX and intXXX >= 0) and negative (intXXX < 0) integers.
|
|
// - Floats are encoded in 4 or 8 bytes (plus a descriptor byte)
|
|
// - Length of containers (strings, bytes, array, map, extensions)
|
|
// are encoded in 0, 1, 2, 4 or 8 bytes.
|
|
// Zero-length containers have no length encoded.
|
|
// For others, the number of bytes is given by pow(2, bd%3)
|
|
// - maps are encoded as [bd] [length] [[key][value]]...
|
|
// - arrays are encoded as [bd] [length] [value]...
|
|
// - extensions are encoded as [bd] [length] [tag] [byte]...
|
|
// - strings/bytearrays are encoded as [bd] [length] [byte]...
|
|
// - time.Time are encoded as [bd] [length] [byte]...
|
|
//
|
|
// The full spec will be published soon.
