Review comment:
@sunchao thank you for your review comments! I changed this part as
suggested. Do you have an example of an assertion checking for a type? The only
thing I could come up with (still quite new to Rust) is something along the
lines of
```
if let Type::PrimitiveType {ref precision, ref scale, .. } = self.schema {
DataType::Decimal(*precision as usize, *scale as usize)
} else {
panic!("Expected a physical type, not a group type")
}
```
