Going through some exercises on basic Rust syntax and ownership.

Rust 101 is a series of videos explaining how to write programs in Rust. The course materials for this series are developed by tweede golf.

These videos are roughly on track with the Reading Club apparently, so this video belongs here this week, I think.

    Shouldn’t we be able to do something like

    let bar : [f32; 5] = [Default::default(); 5];

    ?

    I’m on mobile and too lazy to try whipping up a rust playground example to test this out myself.

      I’ll do you one better!

      let foo: [u8; 10] = Default::default();

      (pretty sure the above only works reliably after they finally were able to derive traits on n-sized arrays but that’s been in for a while now)

      And as you suggested:

      let foo: [u8; 10] = [Default::default(); 10];
