Struct jammdb::BucketData

pub struct BucketData { /* fields omitted */ }

Nested bucket placeholder

This data type signifies that a given key is associated with a nested bucket.alloc You can access the key using the name function. The bucket's name can be used to retreive the bucket using the get_bucket function.

Examples

use jammdb::{DB, Data};

let db = DB::open("my.db")?;
let mut tx = db.tx(true)?;
let bucket = tx.create_bucket("my-bucket")?;

bucket.create_bucket("my-nested-bucket")?;
if let Some(data) = bucket.get("my-nested-bucket") {
    if let Data::Bucket(b) = &*data {
        let name: &[u8] = b.name();
        assert_eq!(name, b"my-nested-bucket");
        let nested_bucket = bucket.get_bucket(b.name()).unwrap();
    }
}
