Creates the Database struct with the fitting logic. Use open for creating/opening one at a specified path or use open_in_memory to only use one in memory.

Lock the AtomicDatabase using read() / write() to access and change it values. The saving of changes will be applied after the used variables are dropped.

use light_magic::db;

db! {
    // `Table` is the identifier that this will use the builtin table type
    // `User` is the table name
    // `{...}` is the table data
    // the first field, like here `id`, is the `primary_key`
    Table<User> => { id: usize, name: String, kind: String },
    // to not use the builtin table type use `Custom` as the identifier of the table
    // using `:` after the table name you can add your own derives
    // like here `PartialEq`
    Custom<Criminal: PartialEq> => { user_name: String, entry: String }
