Struct Mean 

pub struct Mean { /* private fields */ }

The mean. This is only implemented for DecimalWrapper, though it could probably be extended for floating point types.

Trait Implementations

impl Accumulate<DecimalWrapper, DecimalWrapper> for Mean

fn new(item: DecimalWrapper) -> Mean

Creates a new object with an initial value (often based on the value of item.)

fn update(&mut self, item: DecimalWrapper)

Adds a new value to the accumulator.

fn compute(&self) -> Option<DecimalWrapper>

Computes the final value. Returns an option value, which is usually guaranteed to be Some(val) (with the exception of StdDev.)
