Trait linreg::IteratorMean

pub trait IteratorMean<F> {
    fn mean(&mut self) -> Option<F>;
}

Calculate a mean over an iterator

Required Methods

fn mean(&mut self) -> Option<F>

Calculates the mean value of all returned items of an iterator. Returns None if either no items are present or more items than can be counted by F (conversion from usize to F is not possible).

Implementors

• impl<'a, T, I, F> IteratorMean<F> for I where     T: 'a + Into<F> + Clone,     I: Iterator<Item = &'a T>,     F: Float,
