is equvalent of: use std::io::{self, Write}; Also glob operator can be used: use std::collections::*; If we use pub for a whole structure the structure becomes visible, but it's fields are not visible. To make a struct field visible pub must be applied to the field. E.g....

On the other hand, y1 is rendered inaccessible once its value has been moved 4, and any attempt to access it would incur a compiler error. When z goes out of scope 2, the tuple value it contains is dropped, and this in turn drops the value copied from x1 and the one moved from y...

hygiene: Decouple transparencies from expansion IDs And remove fallback to parent modules during resolution of names in scope. This is a breaking change for users of unstable macros 2.0, code like this: ```rust #![feature(decl_macro)] macro m($S: ident) { struct $S; mod m { type A...
This really wants to be struct Buffer<const N: usize, T, CHANNEL> { data: [T; N], .. } though. Hopefully that's not too far off in the future. But this probably a bad idea since panicking destructor is equal to abort (?) I was actually thinking of double / nested panics when...
You can use variable shadowing without moving the original variable to make it inaccessible, but this won't kill any outstanding borrows on its own... fn example() { let mut s = String::new(); let r = &mut s; // Haha, no `mut`! let s = (); // ...drat r.push_str(".....
E.g. #[repr(packed(2))] struct Foo(i16, i32); is a struct with an alignment of 2 bytes and a size of 6 bytes. You can now import an item from a module as an _. This allows you to import a trait's impls, and not have the name in the namespace. E.g. use std::io...
Padding zeroes are now always placed after the sign if it exists and before the digits. With the # flag the zeroes are placed after the prefix and before the digits. Due to the struct field optimisation, using transmute on structs that have no repr attribute or #[repr(Rust)] will no lo...
