How to get blob field data？

[ghost]

when i tried to get a blob data from oracle 11g, I ran into some problems. I googled it, but didn't have a solution. I need help.
My struct:

 struct Template {
    late_id: u32, 
    index_info: String,
    id: u32,
    lib: u8, 
    gender: u8,
    region: u16,
    year: u16,
    template: Vec<u8>,
 }

In the database, the template field corresponds to a blob filed。
Did i should get the blob field like this?if not, how can i get the blob field?

    let mut lib: Vec<Template> = Vec::new();
    while let Some(mut cursor) = stmt.fetch().unwrap() {
        lib.push(Template {
            template_id: cursor.get_data(1).unwrap().unwrap(),
            index_info: cursor.get_data(2).unwrap().unwrap(),
            id: cursor.get_data(4).unwrap().unwrap(),
            lib: cursor.get_data(5).unwrap().unwrap(),
            gender: cursor.get_data(6).unwrap().unwrap(),
            region: cursor.get_data(7).unwrap().unwrap(),
            year: cursor.get_data(9).unwrap().unwrap(),
            template: cursor.get_data(11).unwrap().unwrap(),// here, i couldn't compile it
        })
    }

can somebody help me? thank you!

We simply do not support Vec up to now. There is no particular reason for the missing support other than no one has implemented it yet. I have been away on vacation for the past three weeks, so I see your issue just now. I'm currently working on #41 and my solution is likely to fix this one, too.
