// Generic-slots are pure slots that can be hooked up to signals. They're

// mainly intended to be used in tests where we want to check if a signal

|
|
// lifetime management of the arguments received via callbacks.
|

//
|

|
// Example:
|
||
|
|
// /* Some signal */
|
||
|
|
// sigslot::signal1<int> foo;
|

|
|
//
|

// /* We want to monitor foo in some test */
