colonDB | simpleDB with multiple columns support (database file store)

Checkout main folder for simple key value store. Make sure you clone this repo inside the directory you write in the cargo.toml's [dependencies] simple_db = ... May still contain issues, havent tested enough.

usage

I suggest typing in the first row, which will be used as headers to find stuff based on column headers, in the .txt file before dealing with data.

cargo add colon_db

use colon_db::ColonDB;

Methods:

find save file, or create one

let mut database = ColonDB::find_database("db.txt");

Make sure to .to_string() input values. Check example.

add item or row

database.append_row_to_db("23".to_string(),vec!["a".to_string(),"12".to_string(),"3000".to_string()]);

database.insert_item_into_db("21".to_string(),"name".to_string(), "kak".to_string());
database.insert_item_into_db("21".to_string(),"age".to_string(), "18".to_string());

append a column

db.append_column("status".to_string(), "citizen".to_string());

select a range from the db (0 to total number of rows, vector with column names)

let newdb = database.select_data(Some(4..17), vec!["name".to_string(), "salary".to_string()].into());

get item by key, column

println!("{}",database.select_item("01", "age").unwrap())

delete a row

database.delete_row("09");

display database in terminal

newdb.print_database();
