Trait midas_rs::MidasIterator

pub trait MidasIterator<'a>: 'a + Sized + Iterator<Item = (Int, Int, Int)> {
    fn midas(
        self, 
        rows: Int, 
        buckets: Int, 
        m_value: Int
    ) -> Box<dyn Iterator<Item = Float> + 'a> { ... }

}

Provided methods

fn midas(
    self,
    rows: Int,
    buckets: Int,
    m_value: Int
) -> Box<dyn Iterator<Item = Float> + 'a>

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

For a less ergonomic version, see Midas::iterate.

Panics

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

fn midas_r(
    self,
    rows: Int,
    buckets: Int,
    m_value: Int,
    factor: Float
) -> Box<dyn Iterator<Item = Float> + 'a>

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

For a less ergonomic version, see MidasR::iterate.

Panics

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