Implementations

impl<N, K, L, W, WV, A> Aggregate<N, K, L, W, WV, A>

where N: Field, K: Field, L: Field, W: Field, WV: WeightValue, A: Field,

pub fn builder() -> AggregateBuilder<N, K, L, W, WV, A>

Create an instance of Aggregate using the builder syntax

impl<N, K, L, W, WV, A> Aggregate<N, K, L, W, WV, A>

where N: Field, K: Field, L: Field, W: Field, WV: WeightValue, A: Field,

pub fn new() -> Self

Create a new aggregate instance.

pub fn add<'a, M: ReadMetadata<'a, N, K, L, W, WV, A, AV>, AV: 'a + AnnotationValue>( &'a mut self, item: &'a M, )

Add metadata to the aggregate.

pub fn subtract<'a, M: ReadMetadata<'a, N, K, L, W, WV, A, AV>, AV: 'a + AnnotationValue>( &'a mut self, item: &'a M, )

Subtract metadata from the aggregate.

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

Add another Aggregate’s values to this.

pub fn aggregate(&self, aggregator: &Aggregator<N, K, L, W, A>) -> f64

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

pub fn fraction(&self, aggregator: &Aggregator<N, K, L, W, A>) -> f64

Get a fraction that a field represents with respect to the sum of all fields for a certain aggregator.

pub fn fractions( &self, aggregator: &Aggregator<N, K, L, W, A>, factor: f64, ) -> Vec<f64>

Get all fractions for the given fields with respect to the sum of all fields for a certain aggregator. It can be scaled with a constant factor. Set the factor to 1.0 to ignore scaling.

Trait Implementations

where N: Field + Clone, K: Field + Clone, L: Field + Clone, W: Field + Clone, WV: WeightValue + Clone, A: Field + Clone,

fn clone(&self) -> Aggregate<N, K, L, W, WV, A>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<N, K, L, W, WV, A> Debug for Aggregate<N, K, L, W, WV, A>

where N: Field + Debug, K: Field + Debug, L: Field + Debug, W: Field + Debug, WV: WeightValue + Debug, A: Field + Debug,

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

where N: Field, K: Field, L: Field, W: Field, WV: WeightValue, A: Field,

fn default() -> Self

Returns the “default value” for a type.
