Struct that acts as an interface to an AbortSignal object.

Usage

const std = @import("std");
const zigar = @import("zigar");

const Promise = zigar.function.Promise(error{Aborted}!void);

pub fn start() !void {
    try zigar.thread.use();
}

pub fn stop() void {
    zigar.thread.end();
}

pub fn idle(promise: Promise, signal: zigar.function.AbortSignal) !void {
    const thread = try std.Thread.spawn(.{}, spin, .{ promise, signal });
    thread.detach();
}

pub fn spin(promise: Promise, signal: zigar.function.AbortSignal) void {
    while (signal.off()) {}
    promise.resolve(error.Aborted);
}
