Critical Patterns

Error Handling (REQUIRED)

// ✅ ALWAYS: Use error unions
fn readFile(path: []const u8) ![]u8 {
    const file = try std.fs.cwd().openFile(path, .{});
    defer file.close();
    return try file.readToEndAlloc(allocator, max_size);
}

// Usage with catch
const content = readFile("config.txt") catch |err| {
    std.log.err("Failed: {}", .{err});
    return err;
};
