Why is this unaligned?!
I have a struct of two u64's, and the code that tries ref_from_bytes, crashes, even though alignment is 8, and the slice is a multiple of 8. Even if I try a slice multiple of 16 (336..352 instead of 328..344), it still…

Sorry for the noob question. But I need to use &str, but can't find a way to concatenate it to return a value. I don't know how to implement the as_str() or just & here as instructed here. (click for more details)…
Problem with lifetimes and traits
I keep getting problems with lifetimes when I use a trait, but not when I directly use a type that implements the trait. I have recreated the problem in a few lines of code, with the inferred types shown. struct…
Failed to get address in while loop
Why can't I get address in the while loop? struct Foo { elem1: u32, elem2: String, } fn demo1(x: &mut Foo) { let ref_1 = &mut x.elem1; let ref_2 = &mut x.elem2; let ptr_x = x as *mut Foo; // Ok! } fn demo2(x: &mut Foo)…

#![restrict(unsafe, modules = "platform::win")] (bikesheddable)
I've recently found myself creating a library which includes some platform-specific ffi usage as well as some much higher-level functionality, which I'd really rather not split into 2 crates. This means I cannot…
Borrow checker treating logically immutable reference as mutable
Is there a good reason for the following code to not compile, or is it just a limitation of the borrow checker? And if it is a limit of the borrow checker, is it feasible to un-limit it at some point or should i rely on…
How to represent function with lifetime parameters in trait bounds?
I have a trait (we'll call it WrapFn) that is being implemented for all functions whose parameters satisfy FromValue<'a> and return types satisfy IntoValue<'a>. The point of this trait is to convert a function with…
