Rate Limiting Generator

The rate limiting generator creates a strongly typed RateLimitPolicy<TResult> factory from declarative attributes. It is useful when tenant or route budgets should be visible on a policy host while still producing the same runtime policy as the fluent API.

[GenerateRateLimitPolicy(
    typeof(SearchResponse),
    FactoryMethodName = "CreateGeneratedPolicy",
    PolicyName = "product-search",
    PermitLimit = 2,
    WindowMilliseconds = 60000)]
public static partial class ProductSearchRateLimitPolicy;

The generated factory returns PatternKit.Cloud.RateLimiting.RateLimitPolicy<SearchResponse> and configures the fixed-window permit budget.

Rules

  • The host type must be partial.
  • PermitLimit must be at least 1.
  • WindowMilliseconds must be greater than 0.
  • The generator supports class and struct hosts, including static partial classes.

Diagnostics use the PKRLT prefix.
