Using example Rust EOSIO library, doesn't produce the right SymbolCode

use eosio::*;

#[test]
fn test_symbol_code() {
    assert_eq!(SymbolCode::new(5197638).to_string(), "FOO");
    assert_eq!(Name::from_str("........dxboa").unwrap().as_u64(), 5197638);
}

❌ Failure

failures:

---- abi::test_symbol_code stdout ----

  left: `"SOE"`,

Summary

In some cases we can't just panic when parsing invalid types on chain, due to nodeos bugs.
For example this trx: https://eos.eosq.eosnation.io/tx/ab8690feb4486a030cc16cec6e815108325b292d460b47b8c88b4a75c1959bad

Need a way to parse it into Result.

Basic Example

In addition to Asset::from() -> Self add Asset::from_str() -> Result<Self, Err>

Description

Turns out nodeos allows symbols with > 18 precision when insantiated from smart contract.

Substreams WASM engine doesn't support some things from chrono

Error: rpc error: code = Internal desc = error building pipeline WASM: new wasm module: creating new instance: unknown import: `__wbindgen_placeholder__::__wbindgen_describe` has not been defined

Comes from the chrono dependency in Antelope.rs

chrono = { version = "0.4", features = ["serde"] }

use chrono::{TimeZone, Utc};
