Struct Sources 

pub struct Sources<T> { /* private fields */ }

Several sources for one kind of value.

Implementations

impl<T: Clone> Sources<T>

pub fn new() -> Self

No sources yet.

pub fn with(self, id: impl Into<String>, rank: u8, good_for: Duration) -> Self

Adds a source, or changes the standing of one already known.

pub fn record(&mut self, id: &str, value: T, at: Duration)

Records a reading. at is the receiving clock’s time when it arrived.

An undeclared source is accepted automatically, at the lowest rank and with the same limit as the most recently declared source, so a source added at runtime is still recorded.

pub fn best(&self, now: Duration) -> Option<(&str, Fix<T>)>

The value to use now, and which source it came from.

The highest-ranked live source wins. If no source is live, the most recently heard source is returned instead, marked stale with its age, rather than returning no value at all.

Trait Implementations

impl<T: Clone> Clone for Sources<T>

fn clone(&self) -> Sources<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Sources<T>

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

Formats the value using the given formatter.

impl<T> Default for Sources<T>

fn default() -> Self

Returns the “default value” for a type.
