Struct misc_utils::Max

pub struct Max<T> { /* fields omitted */ }

Helper type to ensure to calculate a maximal value

Methods

impl<T> Max<T> where
    T: Copy + Ord, 

pub fn new() -> Self

Create a new instance

pub fn with_initial(initial: T) -> Self

Create a new instance with an initial value to compare to

pub fn get_max(&self) -> Option<T>

Return the maximal value found so far

Returns None if neither an initial value exists nor update was called. Returns Some(T) if at least one value exists.

pub fn get_max_extreme(&self) -> T where
    T: Bounded, 

Return the maximal value found so far

This method falls back to the minimal value for type T, if no other value exists.

pub fn update<V: Into<Self>>(&mut self, value: V)

Update the value by replacing it with a higher value

If value is greater than self, then self is replaced with value. This method can be called with type T or type Max<T>.
