Struct rpack::Packing

pub struct Packing {
    pub bin_size: u32,
}

Fields

bin_size: u32

Implementations

impl Packing

pub fn new(bin_size: u32) -> Packing

Constructs a new Packing instance

Requires a bin_size<u32> which will be the max size that any bin can fit.

Examples

use rpack::Packing;

let packing = Packing::new(5);

packing will have a bin size of 5.

pub fn pack_items(&mut self, packages: Vec<Item>) -> Vec<Bin>

Main entrypoint for packing bins.

Requires a Vec<Item> representing the sizes of all the bins that will be packed in the bins.

Examples

use rpack::{Bin, Packing, Item};
let items = vec![
    Item{size: 2}, 
    Item{size: 4}, 
    Item{size: 4}, 
    Item{size: 6}, 
    Item{size: 1}
];
let expected = vec![
    Bin{contents:vec![Item{size: 6}]}, 
    Bin{contents:vec![Item{size: 4}, Item{size: 2}]}, 
    Bin{contents:vec![Item{size: 4}, Item{size: 1}]},
];
let mut packing = Packing{bin_size: 6};
let packed_bins = packing.pack_items(items);
    
assert_eq!(packed_bins, expected);
