Repository Generator

[GenerateRepository] emits a factory for InMemoryRepository<TEntity,TKey> from a partial host and a key selector method.

using PatternKit.Generators.Repository;

[GenerateRepository(typeof(OrderRecord), typeof(string), FactoryName = "CreateRepository")]
public static partial class GeneratedOrderRepository
{
    [RepositoryKeySelector]
    private static string SelectKey(OrderRecord order) => order.OrderId;
}

Diagnostics

ID	Meaning
PKREP001	The host type marked with [GenerateRepository] must be partial.
PKREP002	The host must declare exactly one [RepositoryKeySelector] method.
PKREP003	The key selector must be static and return TKey from one TEntity parameter.
