Swevo.AutoGuard

Compile-time guard clauses for .NET.

Apply [AutoGuard] to a partial class with a primary constructor, then decorate constructor parameters with guard attributes:

using AutoGuard;

[AutoGuard]
public partial class CreateOrderCommand(
    [NotNull] string id,
    [NotEmpty] string customer,
    [InRange(1, 100)] int quantity,
    [Matches(@"^[A-Z0-9]+$")] string sku)
{
}

The source generator emits a private field initializer that validates arguments during construction and throws the expected framework exceptions.

Guard attributes

• [NotNull]
• [NotEmpty] for string and IEnumerable<T>
• [InRange(min, max)]
