Tardy

Tardy (def: delaying or delayed beyond the right or expected time; late.) is an asynchronous runtime for writing applications and services in Zig. Most of the code for this project originated in zzz, a performance oriented networking framework.

• Performant: Tardy utilizes the latest Asynchronous APIs while minimizing allocations.
• Portable: Tardy natively supports Linux, Mac and Windows. Easy to port through the custom Async I/O system.
• Scalable: Tardy uses very little memory initially and can be tuned using various configuration options.

Installing

Latest Zig Stable: 0.13.0

Latest Tardy Release: 0.2.0

zig fetch --save git+https://github.com/mookums/tardy#v0.2.0

You can then add the dependency in your build.zig file:

const tardy = b.dependency("tardy", .{
    .target = target,
    .optimize = optimize,
}).module("tardy");

exe.root_module.addImport(tardy);

Important

Tardy is currently alpha software. It's fast and it works but is still experimental!
