namespace JsonApiDotNetCore.Middleware;

/// <summary>
/// Converts action result without parameters into action result with null parameter.
/// <example>
/// <code><![CDATA[
/// return NotFound() -> return NotFound(null)
/// ]]></code>
/// </example>
/// This ensures our formatter is invoked, where we'll build a JSON:API compliant response. For details, see:
/// https://github.com/dotnet/aspnetcore/issues/16969
/// </summary>
[PublicAPI]
public interface IAsyncConvertEmptyActionResultFilter : IAsyncAlwaysRunResultFilter;
