Enum cernan::metric::AggregationMethod

pub enum AggregationMethod {
    Sum,
    Set,
    Summarize,
    Histogram,
}

The available aggregations for Telemetry.

This enumeration signals the way in which Telemetry values will be aggregated. The exact descriptions are detailed below.

Variants

Sum

Cumulatively add Telemetry objects. That is, we store only the summation of all like-points.

Set

Store only the last value of the Telemetry aggregation. The exact ordering within a bin will depend on order of receipt by cernan.

Summarize

Produce a quantile query structure over the Telemetry stream. The method is quantiles::CKMS, a summarization that is cheap in write and read time and has guaranteed error bounds on queries.

Histogram

Produce a binned histogram over the Telemetry stream. The method used is that of quantiles::Histogram, unequal bins with a preference for write over read speed.

Trait Implementations

impl Debug for AggregationMethod

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

Formats the value using the given formatter.

impl Clone for AggregationMethod

fn clone(&self) -> AggregationMethod

Returns a copy of the value.

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

impl Copy for AggregationMethod

impl PartialEq for AggregationMethod

fn eq(&self, other: &AggregationMethod) -> 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 !=.

impl PartialOrd for AggregationMethod

fn partial_cmp(&self, other: &AggregationMethod) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Eq for AggregationMethod

impl Hash for AggregationMethod

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

Feeds this value into the given [Hasher].

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

Feeds a slice of this type into the given [Hasher].
