Feature Toggle Generator

GenerateFeatureToggleSetAttribute creates a typed FeatureToggleSet<TContext> factory from attributed rule methods.

[GenerateFeatureToggleSet(typeof(CheckoutFeatureContext), FactoryName = "CreateToggles", SetName = "checkout-features")]
public static partial class GeneratedCheckoutFeatureToggles
{
    [FeatureToggleRule("new-checkout")]
    private static bool IsBetaTenant(CheckoutFeatureContext context) => context.Tenant == "beta";
}

The generated factory is equivalent to:

FeatureToggleSet<CheckoutFeatureContext>
    .Create("checkout-features")
    .AddRule("new-checkout", false, IsBetaTenant)
    .Build();

Diagnostics:

• PKFT001: host type must be partial.
• PKFT002: at least one [FeatureToggleRule] method is required.
• PKFT003: rule methods must be static and return bool from one context parameter.
