Struct midas_rs::MidasR

pub struct MidasR { /* fields omitted */ }

Methods

impl MidasR

pub fn new(
    MidasRParams { rows: rows, buckets: buckets, m_value: m_value, alpha: alpha }: MidasRParams
) -> Self

pub fn current_time(&self) -> Int

pub fn alpha(&self) -> Float

Factor used to to decay current values when our inputs signal that time has ticked ahead.

pub fn insert(&mut self, (source, dest, time): (Int, Int, Int)) -> Float

Panics

If time < self.current_time()

pub fn query(&self, source: Int, dest: Int) -> Float

pub fn iterate(
    data: impl Iterator<Item = (Int, Int, Int)>,
    params: MidasRParams
) -> impl Iterator<Item = Float>

Takes an iterator of (source, dest, time) thruples and returns an iterator of corresponding scores.

For a more ergonomic version, see MidasIterator::midas_r.

Panics

Subsequent iterator will panic if ever passed a thruple where the third element (the time) decreases from its predecessor.
