Struct partial_function::PartialFunction

pub struct PartialFunction<B, O> where
    B: PartialOrd,  { /* fields omitted */ }

Define a functions defined by multiple functions parts. See BoundedFunction. Uses bounds as [lower,higher], except in the case of a lower bound overlapping a higher bound. In this case, the lower bound always take precedence.

Methods

impl<B, O> PartialFunction<B, O> where
    B: PartialOrd, 

fn new() -> PartialFunctionBuilder<B, O>

Creates a new PartialFunctionBuilder

fn eval(&self, x: B) -> Option<O>

Evaluates the partial function. Returns NAN if no function is defined.
