I just found a serde feature which might simplify the
serialization/deserialization for in-memory/on-disk types. Serde let's you you
define a "from" type which specifies that the annotated type first get's
deserialized into the "from" type and then converted using the `From`
implementation. And it works similarly with an "into" type. This would allow
something like the following:
```rust
/// In memory type
#[serde(from = "TableMetadataUnion", into = "TableMetadataUnion")]
struct TableMetadata {}
impl From<TableMetadataUnion> for TableMetadata {}
impl Into<TableMetadataUnion> for TableMetadata {}
/// on disk types
enum TableMetadataUnion {
V1(TableMetadataV1),
V2(TableMetadataV2)
}
struct TableMetadataV1 {}
struct TableMetadataV2 {}
```
What do you think?
