Is it possible to get SQL_INTERVAL_STRUCT from a cursor?

[joeygibson]

I am working with a Vertica database, and I need to be able to extract its Interval type. I see from the source of this project, several structs related to interval, such as SQL_INTERVAL_STRUCT, but if I try to use this as the type to get_data, like this:

let value = cursor.get_data::<SQL_INTERVAL_STRUCT>(i as u16)?;

I get this compile error:

^^^^^^^^ the trait `odbc::statement::types::OdbcType<'_>` is not implemented for `odbc_sys::SQL_INTERVAL_STRUCT`

I also tried using SQL_INTERVAL_UNION, but got the same error.

I should note that I can read all the other relevant data types from my database, so all my other uses cases are well met by this crate.

Am I doing something wrong, am I missing something, or are these types not usable by a client program?
