Struct NutReader 

pub struct NutReader { /* private fields */ }

Polls upsd, keeping one connection open, and backing off while it is unreachable.

Implementations

impl NutReader

pub fn new(address: &str) -> Self

Reads from upsd at address (“host” or “host:port”, IPv6 addresses in brackets); an empty address disables it.

pub fn read(&mut self, now: Instant) -> Vec<UpsStats>

The UPSes upsd knows, asked again at most every [POLL_EVERY]. Empty when disabled or when upsd was never reached; UPSes read before stay listed, with an error, while upsd does not answer.
