Sleded
A sled-ed database.
Description
a simple crate that exposes a minimalist API for storing persistent data to a file. Backed by sled and serde with RON.
Example
// Something to store, needs to be serializable.
#[derive(Debug, Serialize, Deserialize)]
pub struct Student {
name: String,
value: usize,
}
impl TableLayout for Student {
// adding the name of the stored table.
fn table_name() -> String {
"student".into()
}
}
// storing an item
let db = open("./db").unwrap();
let table = db.table();
let bob_key = table.push(Student {
name: "bob".into(),
value: 0,
});
// query one item
let bob = table.get(&bob_key);
dbg!(bob);
// query all items
for (key, value) in table.iter() {
let key = key.value(&table);
println!("key: {key}, student: {value:?}");
}
// update items
for key in table.keys() {
table.update(&key, |student| {
if let Some(student) = student {
student.value += 1;
}
})
}
