How do I initialize an array of vectors?

Question

I would like to create an array of vectors:

fn main() {
    let v: [Vec; 10] = [Vec::new(); 10];
}

However, the compiler gives me t

You could use the Default trait to initialize the array with default values:

let array: [Vec; 10] = Default::default();

See this playground for a working example.
