Implementations

impl DeviceView

pub fn shares_values(&self, other: &DeviceView) -> bool

True when other holds the very maps of properties and alerts this view holds, as a clone does until either is changed. Constant time; false does not prove the contents differ.

pub fn property(&self, node: &str, property: &str) -> Option<&PropertyView>

The property node/property, when the description declares it.

pub fn properties(&self) -> impl Iterator<Item = (&Id, &Id, &PropertyView)> + '_

Every declared property as (node, property, view), in id order.

pub fn alert(&self, id: &str) -> Option<&str>

The text of alert id, when it is set.

pub fn alerts(&self) -> impl Iterator<Item = (&Id, &str)> + '_

Every set alert as (id, text), in id order.

Trait Implementations

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DeviceView

fn fmt(&self, f: &mut Formatter<'_>) -> Result
