 It is possible to extract a struct from the provider. Internally, this SDK defines a type `StructValue` to store any structure value. The `client.get_struct_value()` functions takes a type parameter `T`. It will try to parse `StructValue` resolved by the provider to `T`, as long as `T` implements trait `TryFrom<StructValue>`.
