Implicit Generics 
Provides a mechanism that allows generic type parameter to be inferred implicitly.
🏃 Quickstart | 📗 Guide | 📦 NuGet
<hr />
Sometimes when developing generic methods extensions it needs additional generic parameter types, and when any of types can not be inferred then all generic parameter types must be specified.
This library brings IOutParam<out T>
interface and OutParam
class to help developers create method
parameters that lets the compiler infer the type of the generic parameter.
Compatibility
Raiqub.ImplicitGenerics is currently compatible with the following frameworks:
- .NET Standard >= 1.0
- .NET 6.0
Quickstart
Reference the package <br/> Add the package to your project, for example via:
Install-Package Raiqub.ImplicitGenerics --or-- dotnet add package Raiqub.ImplicitGenerics
Add using <br/> To use the types provided by this library add using on top of
.cs
file:using Raiqub.ImplicitGenerics
You should now be ready to use the library types on your project.
Guide
To understand the scenarios covered by this library, some examples are given.
Registering adapter on the dependency injector
Take an example of a method that registers an adapter:
public static IServiceCollection AddAdapter<TIn, TOut, TAdapter>(
this IServiceCollection services)
where TAdapter : class, IAdapter<TIn, TOut> =>
services.AddSingleton<IAdapter<TIn, TOut>, TAdapter>();
To call this method all three parameters must be specified:
services.AddAdapter<int, float, Int32ToFloatAdapter>()
But, using the type provided by this library:
public static IServiceCollection AddAdapter<TIn, TOut>(
this IServiceCollection services,
IOutParam<IAdapter<TIn, TOut>> outParam) =>
services.AddSingleton(typeof(IAdapter<TIn, TOut>), outParam.Type);
Then the call is just:
using Raiqub.ImplicitGenerics;
services.AddAdapter(OutParam.Of<Int32ToFloatAdapter>())
Down casting dictionary values
Take another example of a method that down-cast the values of a dictionary:
public static IDictionary<TKey, TOther> DownCastValues<TKey, TValue, TOther>(
this IDictionary<TKey, TValue> dictionary)
where TKey : notnull
where TValue : class
where TOther : class, TValue =>
dictionary
.Select(it => (it.Key, Value: (TOther)it.Value))
.ToDictionary(it => it.Key, it => it.Value);
And to call this method:
IDictionary<string, string> result = dict.DownCastValues<string, object, string>();
But, using the provided IOutParam<out T>
interface:
public static IDictionary<TKey, TOther> DownCastValues<TKey, TValue, TOther>(
this IDictionary<TKey, TValue> dictionary,
IOutParam<TOther> outParam)
where TKey : notnull
where TValue : class
where TOther : class, TValue =>
dictionary
.Select(it => (it.Key, Value: (TOther)it.Value))
.ToDictionary(it => it.Key, it => it.Value);
Finally, the call is:
using Raiqub.ImplicitGenerics;
IDictionary<string, string> result = dict.DownCastValues(OutParam.Of<string>());
