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.

• Tardy utilizes the latest Asynchronous APIs while minimizing allocations.
• Tardy natively supports Linux, Mac, BSD, and Windows.
• Tardy is configurable, allowing you to optimize the runtime for your specific use-case.

?

Tardy is a thread-local asynchronous runtime for Zig, providing the core implementation for asynchronous libraries and services.

• Per-thread Runtime isolation for minimal contention
• Native async I/O (io_uring, epoll, kqueue, poll)
  • File and Dir for Filesystem Operations
  • Socket for Network Operatons

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!
