Trait Handler

pub trait Handler:
    Fn(c_int) -> bool
    + Send
    + Sync { }

This trait is implemented for functions which match the required signature for signal handlers.

The signal number is passed in as a parameter. The handler should return true if the signal was handled, in which case no further action will be taken. If false is returned, then the next handler on the stack will be called, or, if there are no more handlers, the default behaviour for the signal will occur.
