Trait lpc8xx_hal::gpio::direction::Direction

pub trait Direction {
    type SwitchArg;

    fn switch<P: Trait>(_: &Registers<'_>, _: Self::SwitchArg, _: &P) -> Self;
}

Implemented by types that indicate GPIO pin direction

The GpioPin type uses this trait as a bound for its type parameter. This is done for documentation purposes, to clearly show which types can be used for this parameter. Other than that, this trait should not be relevant to users of this crate.

Required Associated Types

type SwitchArg
