https://github.com/msgpack/msgpack-d

is about as simple as it can get:

import std.file;
import msgpack;

struct S { int x; float y; string z; }

void main()
{
     S input = S(10, 25.5, "message");

     // serialize data
     ubyte[] inData = pack(input);

     // write data to a file
     write("file.dat", inData);

     // read data from a file
     ubyte[] outData = cast(ubyte[])read("file.dat");

     // unserialize the data
     S target = outData.unpack!S();

     // verify data is the same
     assert(target.x == input.x);
     assert(target.y == input.y);
     assert(target.z == input.z);
}
