Compiling won't produce an executable just yet because (as stated in the next
paragraph) there are errors. By removing this sentance, the reader won't get
confused when they expect a successful compile i.e. if they don't read ahead one
paragraph, they are going to be checking their code and wondering why it's not
compiling.
After PR #19766 added implicit coersions `*mut T -> *const T`, the explicit casts can be removed.
(The number of such casts turned out to be relatively small).
This removes the extra "the" from the phrase "the the Rust Programming Language book", which isn't particularly grammatical, in stub documents introduced in #20802 to direct users from the old guides to the corresponding sections of the book.
There are a large number of places that incorrectly refer
to deriving in comments, instead of derives.
If someone could look at src/etc/generate-deriving-span-tests.py,
I'm not sure how those tests were passing before/if they were.
These two attributes are used to change the entry point into a Rust program, but
for now they're being put behind feature gates until we have a chance to think
about them a little more. The #[start] attribute specifically may have its
signature changed.
This is a breaking change to due the usage of these attributes generating errors
by default now. If your crate is using these attributes, add this to your crate
root:
#![feature(start)] // if you're using the #[start] attribute
#![feature(main)] // if you're using the #[main] attribute

I realize the linked page still needs an RFC, but the docs should be written in accordance with the guidelines nevertheless.
I searched for times when we were hiding functions with # in the documentation,
and fixed them to not use it unless neccesary.
I also made random improvements whenever I changed something. For example,
I changed Example to Examples, for consistency.
Fixes#13423
Replace deprecated integer suffixes. Remove integer type notations
altogether where possible. Replace uses of deprecated `range()`
function with range notation.
* Use range notation instead of deprecated `range()`
* Remove deprecated `u` integer suffixes used in ranges
* Replace deprecated `i` integer suffixes with `is` for vector numbers
`Thread::spawn()` still gives "use of unstable item" warning which I
hadn't found a way to fix.
