People trait

A People implementation is representative of a collection of Persons. It is implemented by the Elevator and Floor structs. It defines a set of functions for managing Persons in aggregate.

Required Methods

fn gen_num_tips(&self, rng: &mut impl Rng) -> usize

Expected to generate the number of tips to collect from the people

fn get_dest_floors(&self) -> Vec<usize>

Expected to determine the destination floors for all people and return it as a vector.

fn get_num_people(&self) -> usize

Expected to determine the total number of people and return it as a usize.

fn get_num_people_waiting(&self) -> usize

Expected to determine the number of people waiting, that is, not at their desired floor.

fn get_num_people_going_to_floor(&self, floor_to: usize) -> usize

Expected to determine the number of people going to a particular floor

fn get_aggregate_wait_time(&self) -> usize

Expected to read the wait times from people waiting/not at their desired floor and aggregate the total into a usize.

fn are_people_going_to_floor(&self, floor_index: usize) -> bool

Expected to determine whether anyone in the collection of people are going to a given floor, returning a bool which is true if so, and false if not.

fn are_people_waiting(&self) -> bool

Expected to determine whether anyone in the collection of people is waiting/not at their desired floor, returning a bool which is true if so, and false if not.

fn increment_wait_times(&mut self)

Expected to increment the wait times (by 1_usize) among all people waiting/not at their desired floor.

fn reset_wait_times(&mut self)

Expected to reset the wait times (to 0_usize) among all people who have a nonzero wait time and are on their desired floor.

Object Safety

This trait is not object safe.

fn get_aggregate_wait_time(&self) -> usize

Reads the wait times from people waiting/not at their desired floor and aggregates the total into a usize.

fn are_people_going_to_floor(&self, floor_index: usize) -> bool

Determines whether anyone in the collection of people are going to a given floor, and returns a bool which is true if so, and false if not.
