Crate query [−] [src]

query is a simplistic single-table database

This crate provides functionality for very simple databases, you can only have one table in a database, you can't change the data in place and have to load the entire database into memory. But it's really simple.

# Examples

 // get some data to work with
 let data = (0..10).collect();

 // write the data to disk
 let mut db = DB::create("test.db", data)
     .expect("can't create 'test.db'");

 // change the data in memory
 db.iter_mut()
     .for_each(|i| *i * 2);

 // apply the changes
 db.apply()
     .expect("can't update 'test.db'");

 // delete the data in memory
 drop(db);

 // read the database from memory
 let db = DB::load("test.db")
     .expect("can't read 'test.db'");

 // all values have been multiplied by 10
 assert_eq!(db.to_vec(), (0..100).step_by(10).collect());
