CBOR

pkg"add https://github.com/JuliaIO/CBOR.jl.git#sd-round_trip"
using CBOR
using Plots; plotly()
open(io-> write(io, CBOR.encode([2,3,4,5])), "/results/cbor_array", "w");
cbor_array
open(io-> write(io, CBOR.encode(Dict("a" => 22, "b" => 33))), "/results/cbor_dict", "w");
cbor_dict
open(io-> write(io, CBOR.encode("hiiii")), "/results/cbor_string", "w");
cbor_string
open(io-> write(io, CBOR.encode(Pair(7777, "hiiii"))), "/results/cbor_tag", "w");
cbor_tag

Custom Julia Types

open(io-> write(io, CBOR.encode("a" => 22)), "/results/cbor_pair", "w");
cbor_pair
println(CBOR.decode(read(cbor_pair)))
using AbstractPlotting
open(io-> write(io, CBOR.encode(Point2f0(0, 1))), "/results/cbor_point", "w");
cbor_point
CBOR.decode(read(cbor_point)) == Point2f0(0, 1)

Closures:

a = 42
f = (x)-> a + x
f(22)
f2 = CBOR.decode(CBOR.encode(f))
f2(22)

Dict with closure:

d = CBOR.decode(CBOR.encode(Dict("myclosure" => f)))
d["myclosure"](22)

Random type containing Closure (TODO: doesn't yet work because of type missmatch)

d = CBOR.decode(CBOR.encode(f))
typeof(d)
using Serialization
io = IOBuffer(); serialize(io, "asd" => f); seekstart(io); 
typeof(deserialize(io)) |> println
isbitstype(typeof("asd" => f))
 pip install cbor2
