Module callable 

Callable Types

Provides fallible, one-time, zero-argument computations.

A Callable<R, E> is equivalent to FnOnce() -> Result<R, E>, but uses task-oriented vocabulary. Use it when the operation is a computation or task whose success value matters. Use Runnable<E> when the operation only needs to report success or failure.

The trait itself does not require Send; concurrent executors should add + Send + 'static at their API boundary.
