USAGE EXAMPLE
Persist a simple struct.
use structsy::{Structsy, StructsyError, StructsyTx};
use structsy_derive::{queries, Persistent};
#[derive(Persistent, Debug, PartialEq)]
struct MyData {
#[index(mode = "cluster")]
name: String,
address: String,
}
#[queries(MyData)]
trait MyDataQuery {
/// The parameters name have two match the field names and type
/// like the `address` parameter match the `address` field of the struct.
fn search(self, address: String) -> Self;
}
fn main() -> Result<(), StructsyError> {
let db = Structsy::open("example_basic_query.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()?;
let _id = tx.insert(&my_data)?;
tx.commit()?;
let to_find = "https://gitlab.com/tglman/structsy".to_string();
let mut iter = db.query::<MyData>().search(to_find.clone()).into_iter();
let (_id, data) = iter.next().unwrap();
assert_eq!(data.address, to_find);
Ok(())
