kv_cab
Simple persistent generic HashMap/Key-value store, using file locking to limit writing between threads.
This is in a beta state at the moment.
Basic usage:
extern crate kv_cab;
use kv_cab::{ KV, Value };
fn main() {
let mut test_store = KV::<String, Value>::new("./db.cab");
let _ = test_store.insert("key".to_string(), Value::String("value".to_string()));
println!("{:?}", test_store.get("key".to_string()));
let _ = test_store.remove("key".to_string());
}
Usage with user defined Key and Value types:
extern crate kv_cab;
extern crate rustc_serialize;
use kv_cab::KV;
#[derive(Clone, RustcEncodable, RustcDecodable, PartialEq, Eq, Hash)]
enum MyKey {
String(String),
Int(i32),
}
#[derive(Clone, RustcEncodable, RustcDecodable, Debug)]
enum MyValue {
String(String),
Int(i32),
}
fn main() {
let mut test_store = KV::<MyKey, MyValue>::new("./db.cab");
let _ = test_store.insert(MyKey::Int(1i32), MyValue::String("value".to_string()));
println!("{:?}", test_store.get(MyKey::Int(1i32)));
let _ = test_store.remove(MyKey::Int(1i32));
}
