Construct signal with provided / default capacity May throw exception if memory allocation fails

Construct a signal_accumulator as a proxy to a given signal @param signal Signal instance. @param init Initial value of the accumulate algorith

signals are not copy constructible

Get number of connected slots

Number of connected slots.

Construct slim_lock

Construct a slot with no call-back

Count the number of slots connected to this signal @returns The number of connected slots

Construct slot_functor (static method / free function)

Construct storage May throw exception if memory allocation fails

Synchronize internal signal's state - delete logically removed elements according to synchronized stage (if possible). Must be called under write_acce

Try to lock slim_lock. Returns immediately. On successful lock acquisition returns true, otherwise returns false.

* Unblocks signal emission * Safety: thread safe */
