[Goo] FPS Starter Kit
Released
Core/IBlob.cs
Defines an interface IBlob used as a compile-time constraint for blob struct types and a delegate BlobBuilder that returns a root IBlob for a view build. IBlob exposes a static abstract Kind, an optional Key string, and an internal WriteTo method that writes into a Frame.
namespace Goo;
/// <summary>Compile-time constraint for blob struct types. Never use as storage, return, or parameter type (boxes the struct, destroys per-Rebuild allocation profile); only valid in where T : struct, IBlob.</summary>
public interface IBlob
{
static abstract BlobKind Kind { get; }
string? Key { get; }
internal void WriteTo(ref Frame frame);
}
/// <summary>Returns the single root Blob for a GooView build. A named delegate rather than
/// Func<IBlob> because IBlob has a static-abstract member (Kind) and C# bars such interfaces
/// as generic type arguments (CS8920). Consequence for Razor markup: a bare method group cannot
/// bind (its natural type is the illegal Func<IBlob>), so write
/// <c>Build=@(new BlobBuilder(MyBuild))</c>. See docs/site/docs/gotchas.md.</summary>
public delegate IBlob BlobBuilder();
