/**
|
|
* Data format v1
|
|
*
|
|
* Types:
|
|
*
|
|
* Byte 0 to 200: small integer with value (byte - 100)
|
|
* Byte 201: Nil
|
|
* Byte 202: True
|
|
* Byte 203: False
|
|
* Byte 204: Number - IEEE 754 double format
|
|
* Byte 205: String - [u32 length]*[u8... characters]
|
|
* Byte 206: Struct - [u32 length]*2*[value... kvs]
|
|
* Byte 207: Buffer - [u32 capacity][u32 length]*[u8... characters]
|
|
* Byte 208: Array - [u32 length]*[value... elements]
|
|
* Byte 209: Tuple - [u32 length]*[value... elements]
|
|
* Byte 210: Thread - [value parent][u8 state][u32 frames]*[[value callee][value env]
|
|
* [u32 pcoffset][u32 ret][u32 args][u32 size]*[value ...stack]]
|
|
* Byte 211: Table - [u32 length]*2*[value... kvs]
|
|
* Byte 212: FuncDef - [u32 locals][u32 arity][u32 flags][u32 literallen]*[value...
|
|
* literals][u32 bytecodelen]*[u16... bytecode]
|
|
* Byte 213: FuncEnv - [value thread][u32 length]*[value ...upvalues]
|
|
* (upvalues is not read if thread is a thread object)
|
|
* Byte 214: Func - [value parent][value def][value env]
|
|
* (nil values indicate empty)
|
|
* Byte 215: LUdata - [value meta][u32 length]*[u8... bytes]
|
|
* Byte 216: CFunc - [u32 length]*[u8... idstring]
|
|
* Byte 217: Ref - [u32 id]
|
|
* Byte 218: Integer - [i64 value]
|
|
* Byte 219: Symbol - [u32 length]*[u8... characters]
|
|
*
|
|
* This data format needs both a serialization function and deserialization function
|
|
* written in C, as this will load embeded and precompiled programs into the VM, including
|
|
* the self hosted parser abd compiler. It is therefor important that it is correct,
|
|
* does not leak memory, and is fast.
