Struct PartialFunction

Source 
pub struct PartialFunction<B, O> { /* private fields */ }
Expand description

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.

Implementations§

Source§

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

Source

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

Creates a new PartialFunctionBuilder

Source

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

Evaluates the partial function. Returns None if no function is defined.
