Enum Temporality

#[non_exhaustive]
pub enum Temporality {
    Cumulative,
    Delta,
    LowMemory,
}

Defines the window that an aggregation was calculated over.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Cumulative

A measurement interval that continues to expand forward in time from a starting point.

New measurements are added to all previous measurements since a start time.

Delta

A measurement interval that resets each cycle.

Measurements from one cycle are recorded independently, measurements from other cycles do not affect them.

LowMemory

Configures Synchronous Counter and Histogram instruments to use Delta aggregation temporality, which allows them to shed memory following a cardinality explosion, thus use less memory.

Trait Implementations

impl Clone for Temporality

fn clone(&self) -> Temporality

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Temporality

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

Formats the value using the given formatter.

impl Default for Temporality

fn default() -> Temporality

Returns the “default value” for a type.

impl Hash for Temporality

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 Temporality

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

Tests for self and other values to be equal, and is used by ==.

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

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