Example

use massa_serialization::Serializer;

use std::str::FromStr;
use std::collections::BTreeMap;
use massa_models::types::{SetOrDelete, SetOrKeep};
use massa_ledger_exports::{LedgerEntryUpdate, LedgerEntryUpdateSerializer};

let key = "hello world".as_bytes().to_vec();
let mut datastore = BTreeMap::default();
datastore.insert(key, SetOrDelete::Set(vec![1, 2, 3]));
let amount = Amount::from_str("1").unwrap();
let bytecode = Bytecode(vec![1, 2, 3]);
let ledger_entry = LedgerEntryUpdate {
   balance: SetOrKeep::Keep,
   bytecode: SetOrKeep::Set(bytecode.clone()),
   datastore,
};
let mut serialized = Vec::new();
let serializer = LedgerEntryUpdateSerializer::new();
