0.5.0

New Features:

• [#15]: support multi dimensional filter options to be filtered in group

Example:

use venndb::{Any, VennDB};

#[derive(Debug, VennDB)]
pub struct Value {
   #[venndb(filter)]
   pub foo: String,
   pub bar: u32,
}

let db = ValueDB::from_iter([
    Value {
        foo: "a".to_owned(),
        bar: 8,
    },
    Value {
        foo: "b".to_owned(),
        bar: 12,
    },
    Value {
        foo: "c".to_owned(),
        bar: 16,
    },
].into_Iter()).unwrap();

let mut query = db.query();
query.foo(MyString("a".to_owned()));
query.foo(MyString("c".to_owned()));
let values: Vec<_> = query.execute().unwrap().iter().collect();
assert_eq!(values.len(), 2);
assert_eq!(values[0].bar, 8);
assert_eq!(values[0].bar, 16);
