API breakdown

namespace ComputeSharp.D2D1.Interop;

public static class PixelShaderEffect
{
    public static T CreateFromConstantBuffer<T>(ReadOnlySpan<byte> span)
        where T : unmanaged, ID2D1PixelShader, ID2D1PixelShaderDescriptor<T>;

    public static bool TryCreateFromConstantBuffer<T>(ReadOnlySpan<byte> span, out T shader)
        where T : unmanaged, ID2D1PixelShader, ID2D1PixelShaderDescriptor<T>;
}
