  I spent about 1/2 an hour trying to work out why the run function wasn’t visible. Can you spot why? #![cfg(not(any(feature = "vulkan", feature = "dx12", feature = "metal")))] compile_error!("must enable a backend feature"); #[cfg(feature = "dx12")] use gfx_backend_dx12 as back; #[cfg(feature = "metal")] use gfx_backend_metal as back; #[cfg(feature = "vulkan")] use gfx_backend_vulkan as back; use gfx_hal as hal; pub mod path; const DIMS: Extent2D = Extent2D { width: 1024, height: 768,...

  Shifgrethor III: Rooting
  
  from withoutblogs
  
  After the digression in the previous post, it’s time to get back to what I promised in the first post: a look at how shifgrethor handles rooting. Shifgrethor’s solution is somewhat novel and takes advantage of some of Rust’s specific features, so I want to start by looking briefly at some of the other options. How to root a GC’d object There are two broad categories of rooting strategies that are common among precise, tracing garbage collectors:

  Sync but not Send?
  
  from The Rust Programming Language Forum
  
  It’s a relatively simple question (though maybe with not so simple answer), mainly out of curiosity and desire to understand intrinsincs better. We have several types which are Send but not Sync (this is, for example, every Cell-like struct). Reasoning is easy to understand: when the type has interior mutability, we must be sure that we mutate it from one place only, but this place can be everywhere as long as it is singular. But is there any case where the opposite would be sound - i.e., type...

  Multithreading Rust and Wasm
  
  from Rust and WebAssembly
  
  When WebAssembly was first shipped it was an MVP which, while minimal, has spawned a huge number of exciting projects which work today across all major browsers. Rust has capitalized on the wasm MVP’s success as well with tools like wasm-bindgen and wasm-pack by making the MVP feel less minimal. WebAssembly is yet more ambitious, though! Since inception it’s always been intended to extend the WebAssembly specification with new features and functionality.

  Suggestion: a `.take(n)`-like Iterator method that does not take ownership
  
  from The Rust Programming Language Forum
  
  Ever wanted to write this kind of code ? fn main () { let mut iterator = (0 .. 10).into_iter(); for x in iterator.take(3) { println!("{} is in the podium!", x); }; for x in iterator { println!("{} is not, but maybe next time?", x); }; } playground Obviously it cannot work since .take(n) takes (duh) ownership of iterator. This can however be fixed by (mutably) borrowing iterator for the time of that first iteration: fn main () { let mut iterator = (0 ...
