AnyList

AnyList works as a Vec but without generics in it's type.

without having a generic it's type, you can make a list of lists that have different types.

the only issue this creates is having to use the correct type in every function because all of them need a generic, exept for the implementations that don't need it on their arguments(ej: remove, pop).

if a wrong type it's used, then the API will panic.

the only purpose of this is to out perform an Vec<Box>, which generates fragmentation and indirection, with an extra pointer. and to be able to use implementations like pop and remove, without needing generics in their functions.

Example:

 fn main() {
    let mut list = AnyList::new::<u32>();

    list.push::<u32>(1);
    list.insert::<u32>(1, 2);
    list.push::<u32>(3);

    assert_eq!(list.as_slice::<u32>(), &[1,2,3]);

    list.untyped_remove(0);

    assert_eq!(list.as_slice::<u32>(), &[2,3]);

    list.untyped_pop();

    assert_eq!(list.as_slice::<u32>(), &[2]);

    list.insert::<u32>(0, 1);

    for i in 0..list.len() {
      println!("{:?}", list.get::<u32>(i).unwrap())
    }

    assert_eq!(list.as_slice::<u32>(), &[1,2]);
 }
