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

A builder to create an immutable PartialFunction.

Methods

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

pub fn new() -> Self

Creates a new PartialFunctionBuilder.

pub fn with(self, lower: B, func: fn(_: B) -> O) -> Self

Adds a bounded function bounded between [lower,higher[ of function func.

pub fn can_insert(&self, lower: &B) -> bool

Check if you can safely insert into the function list for the specified bounds.

pub fn build(self) -> LowerPartialFunction<B, O>

Builds the PartialFunction from the functions added using with.
