Review Comment:
Just FYI: there's a tool that can make testing a lot more happier
https://github.com/rust-analyzer/expect-test
Basically it's just like
```rust
assert_eq!(format!("{:?}", value.resolve(&schema)), "balabala")
```
We don't manually `match`, but just print out the result.
What's cooler is that `expect_test` can automatically update the actual
result for you.
