Trait BlockOnFuture 

pub trait BlockOnFuture {
    type Output;

    // Required method
    fn block(self) -> Self::Output;
}

Marker trait to block on futures in synchronous code.

This is a simple convenience. Many of the tests in this crate render something and then read a texture in order to perform a diff on the result using a known image. Since reading from the GPU is async, this trait helps cut down boilerplate.

Required Methods
