Struct Aggregate 

pub struct Aggregate {
    pub items: isize,
    pub kinds: BTreeMap<String, isize>,
    pub labels: BTreeMap<String, isize>,
    pub weights: BTreeMap<String, f64>,
    pub annotations: BTreeMap<String, isize>,
}

Fields

items: isize

Over how many items the aggregate has been taken.

kinds: BTreeMap<String, isize>

Kind occurrence.

labels: BTreeMap<String, isize>

Label occurrence.

weights: BTreeMap<String, f64>

Weight sum value.

annotations: BTreeMap<String, isize>

Annotation key occurrence.

Implementations

impl Aggregate

pub fn new(data: &[&Metadata]) -> Self

pub fn add(&mut self, item: &Metadata)

Add metadata to the aggregate.

pub fn subtract(&mut self, item: &Metadata)

Subtract metadata from the aggregate.

pub fn extend(&mut self, other: Self) -> &Self

Add another Aggregate’s values to this.

pub fn sum( &self, aggregator: &Aggregator, fields: Option<&BTreeSet<String>>, absolute: bool, ) -> f64

Get the sum for all given fields’ values for a given aggregator.

pub fn value<S: AsRef<str>>( &self, aggregator: &Aggregator, field: &S, absolute: bool, ) -> f64

Get the value that a field represents for a certain aggregator.

pub fn fraction<S: AsRef<str>>( &self, aggregator: &Aggregator, field: &S, fields: Option<&BTreeSet<String>>, absolute: bool, ) -> f64

Get a fraction that a field represents for a certain aggregator.

pub fn fractions<S: AsRef<str>>( &self, aggregator: &Aggregator, fields: &[S], factor: f64, absolute: bool, ) -> Vec<f64>

Get all fractions for the given fields with respect to each other.

Trait Implementations

impl Clone for Aggregate

fn clone(&self) -> Aggregate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Aggregate

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

Formats the value using the given formatter.

impl Default for Aggregate

fn default() -> Aggregate

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Aggregate

where Aggregate: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Aggregate

fn eq(&self, other: &Aggregate) -> 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.

impl Serialize for Aggregate

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
