A small application for sorting items into different packs based on their weight and quantity.
An item is represented by an ID, a length, a weight and the quantity. A pack is represented by a pack ID, a weight limit and a maximum number of items it can contain.
Packs are created by stacking items in one of three orders:
- In the order they were given, aka
NATURAL - From shortest to longest, aka
SHORT_TO_LONG - From longest to shortest, aka
LONG_TO_SHORT
This application is build using Rust 1.76.0. To install Rust, follow the instructions at https://www.rust-lang.org/tools/install. Once Rust is installed you should be able to call
cargo build
from the workspace directory to build the application. By default it will end up in target/debug/pack-planner, on a
Unix system. Or in target/debug/pack-planner.exe on a Windows system.
Once you have build the application you can run it using
target/debug/pack-planner
When the application starts it will wait for user input. You can add as much input as you like. The program will process the input once you enter an empty line. The program will then output the packing list.
The input is expected to look like
[Sort order],[max pieces per pack],[max weight per pack]
[item id],[item length],[item quantity],[piece weight]
[item id],[item length],[item quantity],[piece weight]
[item id],[item length],[item quantity],[piece weight]
for instance
NATURAL,40,500.0
1001,6200,30,9.653
2001,7200,50,11.21
The output will look like
Pack number: [pack number]
[item id],[item length],[item quantity],[piece weight]
[item id],[item length],[item quantity],[piece weight]
Given the above input this will look like
Pack Number: 1
1001,6200,30,9.653
2001,7200,10,11.21
Pack Length: 7200, Pack Weight: 401.69
Pack Number: 2
2001,7200,40,11.21
Pack Length: 7200, Pack Weight: 448.4
There are a number of unit tests in the test.rs file. You can run these using:
