Struct PinGroup 

pub struct PinGroup { /* private fields */ }

Groups pins and assign given names to each pin, restricting the usage of PinScanner within the group. Implements PinGroup.

Implementations

impl PinGroup

pub fn new( scanner: &Rc<RefCell<PinScanner>>, pins: impl IntoIterator<Item = PinGroupItem>, ) -> Result<Self, Error>

Creates the PinGroup with the scanner managed by Rc of RefCell. Multi-thread operation is unsupported.

WARNING: This does not automatically check the added writable pins against any existing pin group that has the same pin for write access. This is intended for flexibility; check it manually if needed.

pub fn pin_ids(&self) -> impl Iterator<Item = &PinGroupItem>

Iterates through all PinGroupItems in the group, with their given names.

pub fn pin_writable(&self, pin_id: &PinId) -> Result<bool, Error>

Checks if the pin is writable in this group.

pub fn get_pin_id(&self, pin_name: &str) -> Result<PinId, Error>

Gets a pin identifier by its name given in the group.

pub fn get_pin_state(&self, pin_id: &PinId) -> Result<PinState, Error>

Similar to PinScanner::get_pin_state, disabling access to pins outside the group.

pub fn set_pin_state( &mut self, pin_id: &PinId, new_state: Option<bool>, ) -> Result<(), Error>

Similar to PinScanner::set_pin_state, disabling access to pins outside the group, or pins without write access.

pub fn update(&mut self) -> Result<(), Error>

See PinScanner::update.

pub fn write_update(&mut self) -> Result<(), Error>

See PinScanner::write_update. Makes no sense without previous writes.

pub fn batch( &mut self, count: usize, writer: impl FnMut(usize, &mut BsrEdit<'_, '_>) -> Result<(), Error>, reader: impl FnMut(usize, &BsrView<'_, '_>) -> Result<(), Error>, ) -> Result<(), Error>

Similar to PinScanner::batch, disabling access to pins outside the group; disables writes to pins without write access.
