# Zig Generator

This library provides a way to write generators in Zig.

Features:

* Supports async generator functions

* Propagates generator errors

* Return value capture

## Usage

Here's an example of its basic usage:

```zig

const std = @import("std");

const gen = @import("generator");

const Ty = struct {

    pub fn generate(_: *@This(), handle: *gen.Handle(u8)) !u8 {

        try handle.yield(0);

        try handle.yield(1);

        try handle.yield(2);

        return 3;

    }

};

const G = gen.Generator(Ty, u8);

pub const io_mode = .evented;

pub fn main() !void {

    var g = G.init(Ty{});

    std.debug.assert((try g.next()).? == 0);

    std.debug.assert((try g.next()).? == 1);

    std.debug.assert((try g.next()).? == 2);

    std.debug.assert((try g.next()) == null);

    std.debug.assert(g.state.Returned == 3);

}

```
