Use the built cargo for cargotest.
cargotest was using the beta (bootstrap) cargo. This changes it so that it will use the locally built cargo. This is intended to provide a sort of smoke test to ensure Cargo is functional. This *shouldn't* have any real impact on the CI build time. The cargotest job also happens to run cargo's testsuite, so it should already be building cargo.
Note: This will fail until #73266 is merged.
Querify whether a type has structural equality (Take 2)
Alternative to #72177.
Unlike in #72177, this helper method works for all types, falling back to a query for `TyKind::Adt`s that determines whether the `{Partial,}StructuralEq` traits are implemented.
This is my preferred interface for this method. I think this is better than just documenting that the helper only works for ADTs. If others disagree, we can just merge #72177 with the fixes applied. This has already taken far too long.
Clarify the behaviour of Pattern when used with methods like str::contains
Fixes#45507.
I used the previous work by @Emerentius (thanks !), added a paragraph and checked the links (they work for me but I'm not against someone else checking them too).
These lead to inference regressions (mostly in tests) in code that looks
like:
let socket = std::net::SocketAddrV4::new(std::net::Ipv4Addr::new(127, 0, 0, 1), 8080);
assert_eq!(socket, "127.0.0.1:8080".parse().unwrap());
That compiles as of stable 1.44.0 but fails in beta with:
error[E0284]: type annotations needed
--> src/main.rs:3:41
|
3 | assert_eq!(socket, "127.0.0.1:8080".parse().unwrap());
| ^^^^^ cannot infer type for type parameter `F` declared on the associated function `parse`
|
= note: cannot satisfy `<_ as std::str::FromStr>::Err == _`
help: consider specifying the type argument in the method call
|
3 | assert_eq!(socket, "127.0.0.1:8080".parse::<F>().unwrap());
|
Previously, some doctests were spawning new threads and joining them to
indicate that a particular call should panic; this hurt readability, so
the tests have been adjusted to simply call the method and use the
`should_panic` marker.
This helper method works for all types, falling back to a query for
`TyKind::Adt`s to determine whether the implement the
`{Partial,}StructuralEq` traits.
Allow inference regions when relating consts
As first noticed by @eddyb, `super_relate_consts` doesn't need to check for inference vars since `eval` does it already (and handles lifetimes correctly by erasing them).
Fixes#73050

expand: More precise locations for expansion-time lints
First commit: a macro expansion doesn't have a `NodeId` associated with it, but it has a parent `DefId` which we can use for linting.
The observable effect is that lints associated with macro expansions can now be `allow`ed at finer-grained level than whole crate.
Second commit: each macro definition has a `NodeId` which we can use for linting, unless that macro definition was decoded from other crate.
Enable AVR as a Tier 3 target upstream
Tracking issue: #44052.
Things intentionally left out of the initial upstream:
* The `target_cpu` flag
I have made the cleanup suggestions by @jplatte and @jplatte in 043550d9db.
Anybody feel free to give the branch a test and see how it fares, or make suggestions on the code patch itself.
Add comment about LocalDefId -> DefId
Now there are instructions on how to convert back and forth on both
structs, not just one.

Add various Zulip notifications for prioritization
Adapts `triagebot.toml` for rust-lang/triagebot#616 and adds various Zulip notifications for the Prioritization WG workflow.
We should also add indications about the procedure for handling those events, cc @rust-lang/wg-prioritization.
r? @spastorino
This should be merged as soon as possible after rust-lang/triagebot#616 is merged, cc @Mark-Simulacrum
Provide suggestion to convert numeric op LHS rather than unwrapping RHS
Given a code
```rust
fn foo(x: u8, y: u32) -> bool {
x > y
}
fn main() {}
```
it could be more helpful to provide a suggestion to do "u32::from(x)"
rather than "y.try_into().unwrap()", since the latter may panic.
We do this by passing the LHS of a binary expression up the stack into
the coercion checker.
Closes#73145
