unsafe

Background We've been using some code copied verbatim from Joe Duffy's "Concurrent Programming on Windows" (page 149) in production for over a year. The code (below) is used in our Asp.Net web application to probe if there's enough stack space. Our site allows users to script out their own web pages and control logic in a simple proprietry scripting language - it's possible for a user to script something nasty and cause a stackoverflow exception, so we use Duffy's code example to stop execution of the errant script before the uncatchable StackOverflow exception takes down the whole IIS AppPool

I don't have a particularly solid understanding of Rust's aliasing rules (and from what I've heard they're not solidly defined), but I'm having trouble understanding what makes this code example in the std::slice documentation okay. I'll repeat it here: let x = &mut [1, 2, 4]; let x_ptr = x.as_mut_ptr(); unsafe { for i in 0..x.len() { *x_ptr.offset(i as isize) += 2; } } assert_eq!(x, &[3, 4, 6]); The problem I see here is that x , being an &mut reference, can be assumed to be unique by the compiler. The contents of x get modified through x_ptr , and then read back via x , and I see no reason

I created a class library today with the new Class Library (Package) templates in Visual Studio 2015. Apparently it uses a fancy new project format, the ASP.NET xproj, for building the package. While that's fine by me, how do I call unsafe code from the library? I looked into Project > Properties > Build , where the option to toggle unsafe code should be, but all I got was this: So yeah, no such luck. I even tried pasting "<AllowUnsafeBlocks>true</AllowUnsafeBlocks>" manually into the .xproj file, but the compiler still complains. Is it possible to enable this without creating another non

EDIT: You can use unsafe code... you just have to manually edit the proj file. Why or why does C# on WP8 not support unsafe code when I can use native C++ code on the phone(I did not expect this)? I mean rly come on, I am so disappointed with what Microsoft is trying to force C# into. Is there any MS plans to support this in the future on WP8? I pass shader constants from C# to C++ and use unsafe code to optimize this process but on WP8 i'm going to be forced into doing this in some slow fashion on a WAY slower device compared to a PCs and it makes this very frustrating. As an example to pass
