Crate structsy

Simple single file struct persistence manger

Example

use structsy::{Structsy, StructsyError, StructsyTx};
use structsy_derive::Persistent;
#[derive(Persistent)]
struct MyData {
    name: String,
    address: String,
}
// ......
let db = Structsy::open("my_data.db")?;
db.define::<MyData>()?;

 let my_data = MyData {
   name: "Structsy".to_string(),
   address: "https://gitlab.com/tglman/structsy".to_string(),
};
let mut tx = db.begin()?;
tx.insert(&my_data)?;
tx.commit()?;
