to be able to set a marker/id on the socket for network filtering (iptables/ipfw here) purpose.
I refactored the code: - Removed handling of methods, as it felt entirely unnecessary - Removed clippy utils (obviously...) - Used some shiny compiler features (let-else is very handy for lints 👀) - I also renamed the lint to `for_loop_over_fallibles` (note: no `s`). I'm not sure what's the naming convention here, so maybe I'm wrong.
if the iterator is used after the loop, we need to use `.by_ref()`
The loop could contain `break;` that won't work with an `if let`
Those are basically the same but the first one seems to fit better
The macro warn_ was named like that because it the keyword warn is a built-in attribute and at the time this macro was created the word 'warning' was also taken. However it is no longer the case and we can rename warn_ to warning.
…rminal The UNIX and WASI implementations use `isatty`. The Windows implementation uses the same logic the `atty` crate uses, including the hack needed to detect msys terminals. Implement this trait for `File` and for `Stdin`/`Stdout`/`Stderr` and their locked counterparts on all platforms. On UNIX and WASI, implement it for `BorrowedFd`/`OwnedFd`. On Windows, implement it for `BorrowedHandle`/`OwnedHandle`. Based on rust-lang#91121 Co-authored-by: Matt Wilkinson <mattwilki17@gmail.com>
If a process has no console, it'll have NULL in place of a console handle, so return early with `false` in that case without making any OS calls.
Rather than referencing a slice's pointer and then creating a new slice with a longer length, offset from the base structure pointer instead. This makes some choices of Rust semantics happier.
… r=joshtriplett Support parsing IP addresses from a byte string Fixesrust-lang#94821 The goal is to be able to parse addresses from a byte string without requiring to do any utf8 validation. Since internally the parser already works on byte strings, this should be possible and I personally already needed this in the past too. ~~I used the proposed approach from the issue by implementing `TryFrom<&'a [u8]>` for all 6 address types (3 ip address types and 3 socket address types). I believe implementing stable traits for stable types is insta-stable so this will probably need an FCP?~~ Switched to an unstable inherent method approach called `parse_ascii` as requested. cc `@jyn514`
socket `set_mark` addition. to be able to set a marker/id on the socket for network filtering (iptables/ipfw here) purpose.
… r=thomcc Add `IsTerminal` trait to determine if a descriptor or handle is a terminal The UNIX implementation uses `isatty`. The Windows implementation uses the same logic the `atty` crate uses, including the hack needed to detect msys terminals. Implement this trait for `Stdin`/`Stdout`/`Stderr`/`File` on all platforms. On Unix, implement it for `BorrowedFd`/`OwnedFd`. On Windows, implement it for `BorrowedHandle`/`OwnedHandle`. Based on rust-lang#91121 Co-authored-by: Matt Wilkinson <mattwilki17@gmail.com>
Replace `Body::basic_blocks()` with field access Since the refactoring in rust-lang#98930, it is possible to borrow the basic blocks independently from other parts of MIR by accessing the `basic_blocks` field directly. Replace unnecessary `Body::basic_blocks()` method with a direct field access, which has an additional benefit of borrowing the basic blocks only.
Uplift `clippy::for_loops_over_fallibles` lint into rustc
This PR, as the title suggests, uplifts [`clippy::for_loops_over_fallibles`] lint into rustc. This lint warns for code like this:
```rust
for _ in Some(1) {}
for _ in Ok::<_, ()>(1) {}
```
i.e. directly iterating over `Option` and `Result` using `for` loop.
There are a number of suggestions that this PR adds (on top of what clippy suggested):
1. If the argument (? is there a better name for that expression) of a `for` loop is a `.next()` call, then we can suggest removing it (or rather replacing with `.by_ref()` to allow iterator being used later)
```rust
for _ in iter.next() {}
// turns into
for _ in iter.by_ref() {}
```
2. (otherwise) We can suggest using `while let`, this is useful for non-iterator, iterator-like things like [async] channels
```rust
for _ in rx.recv() {}
// turns into
while let Some(_) = rx.recv() {}
```
3. If the argument type is `Result<impl IntoIterator, _>` and the body has a `Result<_, _>` type, we can suggest using `?`
```rust
for _ in f() {}
// turns into
for _ in f()? {}
```
4. To preserve the original behavior and clear intent, we can suggest using `if let`
```rust
for _ in f() {}
// turns into
if let Some(_) = f() {}
```
(P.S. `Some` and `Ok` are interchangeable depending on the type)
I still feel that the lint wording/look is somewhat off, so I'll be happy to hear suggestions (on how to improve suggestions :D)!

…name-attr-warning, r=davidtwco translations: rename warn_ to warning ## Description This MR renames the the macro `warn_` to `warning`. To give a little bit of context, as [explained](https://rust-lang.zulipchat.com/#narrow/stream/336883-i18n/topic/.23100717.20diag.20translation/near/295074146) by ``@davidtwco`` in the Zulip channel, `warn_` was named like that because the keyword `warn` is a built-in attribute and at the time this macro was created the word `warning` was also taken. However, it is no longer the case and we can rename `warn_` to `warning`.
