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:
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);
}
