meiose, a C++14 MessagePack (and JSON) de/serialization library

The core component of the library is the meiose::variant, a tagged union container supporting the types of the MessagePack specification.

Use the read and write functions of the msgpack and json sub-namespaces to read and write from and to std::{i,o}stream, respectively.

meiose does not support streamed/partial reading or writing of values, it can only read them or write them all at once.

Build systems

Multiple build system files are available for easy integration of the library among other codebases. By default, all build system compiles meiose statically

  • CMake: this is the main supported build system. Exports the following library names:
    • meiose-static if MEIOSE_BUILD_STATIC is true (default).
    • meiose is MEIOSE_BUILD_SHARED is true.
  • Meson: defines the following dependency variables:
    • meiose_static if option static is true (default).
    • meiose if option shared is true.
  • QMake: always builds a meiose library. Static by default, unless meiose-shared CONFIG is set.

MsgPack type ↔ C++ type conversion

MsgPack type C++ type
Integer int64_t
Nil nullptr_t
Boolean bool
Float double
String std::string
Binary std::vector<uint8_t>
Array std::vector<meiose::variant>
Map std::map<meiose::variant, meiose::variant>
Extension std::pair<int8_t, std::vector<uint8_t>>
