Not great as of now, will get better in subsequent releases. If you want examples, please head to the benches folder.

Native derive

With the derive feature, the native traits can be derived without going through Serde. Attributes are under #[cbor(...)].

use seabored::de::from_bytes;
use seabored::ser::CborSerialize;

#[derive(Debug, PartialEq, seabored::CborSerialize, seabored::CborDeserialize)]
struct Record {
    id: u32,
    #[cbor(key = "payload", tag = 24)]
    payload: Vec<u8>,
    #[cbor(skip, default)]
    cache: u64,
}

let bytes = Record { id: 1, payload: vec![1, 2],…
