Method get_attribute

Returns information about this device. # Example ``` # use cust::*; # use std::error::Error; # fn main() -> Result<(), Box > { # init(CudaFlags::empty())?; use cust::device::{Device, DeviceAttribute}; let device = Device::get_device(0)?; println!("Max Threads Per Block: {}", device.get_attribute(DeviceAttribute::MaxThreadsPerBlock).unwrap()); # Ok(()) # } ```

    /// # }

                &mut val as *mut i32,
                // This should be safe, as the repr and values of DeviceAttribute should match.
