How to: Extract date using get

[cstrickland-pag]

Hi,

I am hoping to extract a date variable from row, using something along the lines of:

let value: Option<f64> = row.get::<f64, _>(field_name_str);

When trying different options I get:

= help: the following other types implement trait `FromSql<'a>`:
          &'a XmlData
          &'a [u8]
          &'a str
          bool
          f32
          f64
          i16
          i32
        and 4 others

note: required by a bound in tiberius::Row::get

How do I extract the date from the row?

Thanks in advance,

Chris
