Trait StreamingStatistic

pub trait StreamingStatistic {
    type Type;

    // Required methods
    fn add_sample(&mut self, sample: Self::Type) -> Self::Type;
    fn get_last_sample(&self) -> Self::Type;
    fn get_last_result(&self) -> Self::Type;
    fn get_num_samples(&self) -> u64;
}

A statistic type that can be incrementally calculated after each sample is added. Does not necessarily have to have the full set of data available to it, and as such, should be fast.

Required Methods

fn add_sample(&mut self, sample: Self::Type) -> Self::Type

adds a sample to this streaming statistic, returning a result of the operation.

fn get_last_sample(&self) -> Self::Type

Returns a copy of the last sample added

fn get_last_result(&self) -> Self::Type

Returns the last value returned by ‘add_sample’

fn get_num_samples(&self) -> u64

Returns the total number of samples pushed in
