Ziggy Pack

Ziggy Pack is a message pack library for zig written is zig. Ziggy Pack uses compile time reflection to get buffer size, pack and (soon)unpack.

Basic usage

const std = @import("std");
const pack = @import("ziggy-pack.zig");

const testmsg = struct {
    a: [5]u32 = [_]u32{
    f: bool = false,
    nil: @Type(.Null) = null,
    int32: i32 = -3,
    unt64: u64 = 4,
};

pub fn main() !u8 {
    const testmsg1 = testmsg{};
    // get the size of the buffer you'll need
    const ps = pack.packSize(testmsg1);
    var a = [_]u8{0} ** ps;

    // pack the struct
    var i: usize = 0;
    pack.pack(a[0..a.len], &i, testmsg1);

    return 0;
}
