I am trying to split my project into multiple files but I am having problems importing them into my `main.rs` as it says the Column's fields are private but I have declared the struct as public. 

src/column.rs

```
pub struct Column {
    name: String,
    vec: Vec<i32>,
}

```

src/main.rs

```
pub mod column;

fn main() {
    let col = column::Column{name:"a".to_string(), vec:vec![1;10]};
    println!("Hello, world!");
}

```

cargo build 

```
src/main.rs:4:15: 4:75 error: field `name` of struct `column::Column` is private
src/main.rs:4     let col = column::Column{name:"a".to_string(), vec:vec![1;10]};
                            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
