ResultZero

NuGet

Zero-allocation result pattern for C#.

Normally, exceptions are a great choice for error handling in C#. However, they can be notoriously slow when used for control flow. The result pattern can be better for:

  • Parsers that are expected to handle erroneous input
  • Validating user input in server APIs

ResultZero is designed with the following goals in mind:

  • Zero memory allocation for both success and error cases
  • No redundant features or bloat
  • Scalable for all use cases

Example

static Result<int> Divide(int Numerator, int Denominator) {
    if (Denominator == 0) {
        return new Error("Cannot divide by zero.");
    }
    return Numerator / Denominator;
}

// Unwrap results, throwing if error
Console.WriteLine(Divide(10, 2).Value);

// Check if results errored
if (Divide(10, 0).IsError) {
    Console.WriteLine("Denominator was 0");
}

// Advanced error handling
if (Divide(3, 1).TryGetValue(out int Value, out Error Error)) {
    Console.WriteLine(Value);
}
else {
    Error.Throw();
}
