| class | CountingDebouncer |
| This debouncer will count the ON values and if the number of ON values in a given window exceeds a threshold, then triggers. More... | |

| class | ToggleDebouncer< Debouncer > |
| This class acts as a debouncer that uses one momentary input button, and switches the event state at every rising edge of that input button. More... | |

Strategy classes for debouncing inputs.
A Debouncer is a class that input object will use as a template. The debouncer class may have arbitrary class-local state, and there will be one object of it per input bit. The debouncer will be periodically updated when polling the input state. For each update the debouncer has to decide whether the state has changed (and the new update should be published) or the state has not changed or the update shold be ignored.
A debouncer class has to have the following public methods:
// A structure that captures the parameters. typedef ... Options;
// Constructor from the parameters. explicit Debouncer(const Options& opts);
// returns the last known state bool current_state();
// called once after construction void initialize(bool state);
// called when an on-network event comes to change the state void override(bool new_state);
// returns true if measurement should be published as the new state. bool update_state(bool measurement);
