12/// Convenience macro for turning a CUDA error code into a `std::result::Result`.
13///
14/// # Usage
15///
16/// There are two possible uses of the macro:
17///
18/// (1) Shorthand to return `Ok(something)` or a CUDA error:
19///
20/// ```ignore
21/// result!(code, return_value);
22/// ```
23///
24/// (2) Shorthand to return `Ok(())` or a CUDA error:
25///
26/// ```ignore
27/// result!(code)
28/// ```
