Implementations

impl Diagnostic

pub fn add_measurement(&mut self, value: f64)

Add a new value as a DiagnosticMeasurement. Its timestamp will be Instant::now.

pub fn new(
    id: DiagnosticId,
    name: impl Into<Cow<'static, str>>,
    max_history_length: usize
) -> Diagnostic

Create a new diagnostic with the given ID, name and maximum history.

pub fn with_suffix(self, suffix: impl Into<Cow<'static, str>>) -> Diagnostic

Add a suffix to use when logging the value, can be used to show a unit.

pub fn measurement(&self) -> Option<&DiagnosticMeasurement>

Get the latest measurement from this diagnostic.

pub fn value(&self) -> Option<f64>

Get the latest value from this diagnostic.

pub fn average(&self) -> Option<f64>

Return the mean (average) of this diagnostic’s values. N.B. this a cheap operation as the sum is cached.

pub fn history_len(&self) -> usize

Return the number of elements for this diagnostic.

pub fn duration(&self) -> Option<Duration>

Return the duration between the oldest and most recent values for this diagnostic.

pub fn get_max_history_length(&self) -> usize

Return the maximum number of elements for this diagnostic.

pub fn values(&self) -> impl Iterator<Item = &f64>

pub fn measurements(&self) -> impl Iterator<Item = &DiagnosticMeasurement>

pub fn clear_history(&mut self)

Clear the history of this diagnostic.

Trait Implementations

impl Debug for Diagnostic

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

Formats the value using the given formatter.
