Enum opentelemetry::sdk::metrics::InstrumentKind

pub enum InstrumentKind {
    Counter,
    UpDownCounter,
    Histogram,
    ObservableCounter,
    ObservableUpDownCounter,
    ObservableGauge,
}

The identifier of a group of instruments that all perform the same function.

Variants

Counter

Identifies a group of instruments that record increasing values synchronously with the code path they are measuring.

UpDownCounter

A group of instruments that record increasing and decreasing values synchronously with the code path they are measuring.

Histogram

A group of instruments that record a distribution of values synchronously with the code path they are measuring.

ObservableCounter

A group of instruments that record increasing values in an asynchronous callback.

ObservableUpDownCounter

A group of instruments that record increasing and decreasing values in an asynchronous callback.

ObservableGauge

a group of instruments that record current values in an asynchronous callback.

Trait Implementations

impl Clone for InstrumentKind

fn clone(&self) -> InstrumentKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for InstrumentKind

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

Formats the value using the given formatter.

impl Hash for InstrumentKind

fn hash<__H>(&self, state: &mut __H)where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for InstrumentKind

fn eq(&self, other: &InstrumentKind) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
