Function install_db_dir_lib 

pub fn install_db_dir_lib(cx: &mut Cx) -> Result<Value>

Open a fresh db-directory store and return its root DbDir wrapped as an opaque table/directory object.

Errors

Returns a capability error if the table/db capability has not been granted to cx. Note that the individual read, write, mkdir, and rmdir operations on the returned directory are gated by their own capabilities.

Examples

use std::sync::Arc;
use sim_kernel::{
    Cx, DefaultFactory, EagerPolicy, Symbol, Table,
    capability::{table_db_capability, table_db_read_capability, table_db_write_capability},
};
use sim_table_db::install_db_dir_lib;

let mut cx = Cx::new(Arc::new(EagerPolicy), Arc::new(DefaultFactory));
cx.grant(table_db_capability());
cx.grant(table_db_read_capability());
cx.grant(table_db_write_capability());

let root = install_db_dir_lib(&mut cx).unwrap();
let table = root.object().as_table_impl().unwrap();
let value = cx.factory().string("v".to_owned()).unwrap();
table.set(&mut cx, Symbol::new("k"), value.clone()).unwrap();
assert_eq!(table.get(&mut cx, Symbol::new("k")).unwrap(), value);
