Exposing Rust types and functions to C API consumers.

It’s impossible to make the declarations below follow the order I talked through them on the recording without also making them horrible to read, so just use this outline instead:

  1. add_in_rust
  2. Strings
    1. concat_strings
    2. free_rust_string
  3. Point
    1. point_translate
  4. union
  5. OpaquePoint

e030: Can You See Me Now?27 avr. 201900:18:37

Item visibility and pub(<restricted>) as API design tools.

Show Notes

The easiest and most effective way to understand the example in this case will simply be to look directly at the source code. You can read the docs for each of the nested modules, but you’ll be doing a lot of navigating around for that.

Also, I am using Cargo’s --document-private-items flag, so that you can see all the items in all the modules, even those which are not public, but note that usually you would not see docs for those!

Show Notes

The code samples here directly match the things I described in the show, so you will likely want to look at add and ffi::add, then Point, translate, and ffi::translate in that order.

e027: Trust Me; I Promise!01 déc. 201800:21:27

An intro to unsafe Rust and Rust’s idea of safety.

Show Notes Errata

A quick correction: on the show I said that a trait needed to be unsafe when it had an unsafe fn method. This isn’t correct: safe traits can have unsafe methods, and unsafe traits can exist without any methods at all (as implied by my reference to Send and Sync). You can see this in practice in the following example, which compiles just fine!

trait ASafeTrait { unsafe fn unsafe_method() {} } unsafe AnUnsafeTrait {}

The idea of an unsafe trait is that it has some conditions which you must uphold to safely implement it – again, just as with Send and Sync. In the case of most traits, this will be because some trait method has invariants it needs to hold else it would cause undefined behavior. For another example of this, see the (unstable as of the time of recording) trait std::iter::TrustedLen.

Thanks to Rust language team member @centril for noting this to me after listening when I was recording the show live!

Links Examples Borrow-checked code in unsafe let mut f = String::from("foo"); unsafe { let borrowed = &mut f; let borrow_again = &f; println!("{}", borrowed); // This would be unsafe and throw an error: // println!("{}", borrow_again); }

(See it in a playground)

Safely mutating a raw pointer let f = Box::new(12); let mut g = Box::into_raw(f); g = &mut (g + 10);

You can see all of the pieces of the final example described in the show here (and the module has the required definitions for Point).

let points = vec![ Point { x: 1.0, y: 2.0 }, Point { x: 12.0, y: 4.3 }, Point { x: -5.4, y: 18.7 }, ]; # let origin = Point::default(); # // This is the version we start with. It works fine, but it's not elegant. let distances_inline: Vec<f32> = points .iter() .map(|point| { let change = point - &origin; (change.x.powi(2) + change.y.powi(2)).sqrt() }) .collect(); # // This version is *much* cleaner! let distances_impl: Vec<f32> = points.iter().map(distance_from_impl(&origin)).collect(); Sponsors
