Struct Port 

pub struct Port(/* private fields */);

Available on crate feature cgb only.

The port, open and drawing current.

Dropping this leaves it that way. close is what puts it back down.

Implementations

impl Port

pub fn led(&self, on: bool)

Turn the lamp on or off.

pub fn signal(&self) -> bool

Whether infrared is reaching the sensor.

This Game Boy’s own lamp reaches its own sensor, so led registers here as readily as anything across the room.

pub fn close(self)

Close the port.

The reading half draws current for as long as it is open, which is what this is for.
