Struct ErasedPin 

pub struct ErasedPin<MODE> { /* private fields */ }

A pin whose identity has moved into runtime values, keeping its mode.

Port and number become fields, so pins of different ports share a type and fit in one array. MODE stays a type parameter — an ErasedPin<Input> still has no set_high. One-way: the checks that need the exact pin have already run by the time it is erased.

Implementations

impl<MODE> ErasedPin<MODE>

pub fn port(&self) -> Port

Returns which port the pin came from.

pub fn number(&self) -> u8

Returns the pin’s number within its port.

impl<OTYPE> ErasedPin<Output<OTYPE>>

pub fn set_high(&mut self)

Drives the pin high.

pub fn set_low(&mut self)

Drives the pin low.

pub fn toggle(&mut self)

Inverts the driven level.

pub fn is_set_high(&self) -> bool

Returns whether the pin is being driven high.

Reads back OCTL, i.e. what was last written, not what the wire is at — for the latter on an open-drain pin see is_high.

pub fn is_set_low(&self) -> bool

Returns whether the pin is being driven low.

impl ErasedPin<Input>

pub fn is_high(&self) -> bool

Returns whether the input reads high.

pub fn is_low(&self) -> bool

Returns whether the input reads low.

impl ErasedPin<Output<OpenDrain>>

pub fn is_high(&self) -> bool

Returns whether the wire reads high.

Open-drain can only pull low, so this is the actual line level, which another device on a shared bus may be holding down.

pub fn is_low(&self) -> bool

Returns whether the wire reads low.
