PeregrineDB
Peregrine DB is an in-memory thread-safe data store library for Rust.
Usage:
In cargo.toml:
[dependencies]
peregrine_db = {git = "https://github.com/MarshallBelles/PeregrineDB"}
In .rs:
use peregrine_db::PeregrineDB;
use std::collections::HashMap;
use futures::executor::block_on;
#[macro_use]
extern crate log;
async fn peregrine_example() {
// initialize new DB
let db: PeregrineDB = PeregrineDB::new();
info!("PeregrineDB initialized");
// save some data
let mut data = HashMap::new();
data.insert("hello".to_string(), "world".to_string());
let response = db.write(data).await.unwrap();
info!("Saved data");
// read the data
let mut keys = vec![];
keys.push("hello".to_string());
let stored_data = db.read(keys).await.unwrap();
info!("Read data");
// write and read should be the same
assert_eq!(stored_data, response);
info!("{:?} == {:?}", stored_data, response);
}
fn main() {
env_logger::init_from_env(
env_logger::Env::default().filter_or(env_logger::DEFAULT_FILTER_ENV, "info"));
block_on(peregrine_example());
}
