Struct InOutPin 

Source 
pub struct InOutPin<T>
where
    T: AnyPin,
{ /* private fields */ }
Expand description

A wrapper AnyPin<Function = FunctionSioOutput> emulating open-drain function.

This wrapper implements both InputPin and OutputPin, to simulate an open-drain pin as needed for example by the wire protocol the DHT11 sensor speaks.
