This means that any candidates which rely on `V` only make +// progress in the second iteration, allowing a cache access in the first iteration to take +// precedence. +// +// tl;dr: our caching of coinductive cycles was broken and this is a regression +// test for that. + +#[rustc_coinductive] +trait Trait<T: ?Sized, V: ?Sized, D: ?Sized> {} +struct A<T: ?Sized>(*const T); +struct B<T: ?Sized>(*const T); + +trait IncompleteGuidance<T: ?Sized, V: ?Sized> {} +impl<T: ?Sized, U: ?Sized + 'static> IncompleteGuidance<U, u8> for T {} +impl<T: ?Sized, U: ?Sized + 'static> IncompleteGuidance<U, i8> for T {} +impl<T: ?Sized, U: ?Sized + 'static> IncompleteGuidance<U, i16> for T {} + +trait ImplGuidance<T: ?Sized, V: ?Sized> {} +impl<T: ?Sized> ImplGuidance<u32, u8> for T {} +impl<T: ?Sized> ImplGuidance<i32, i8> for T {} + +impl<T: ?Sized, U: ?Sized, V: ?Sized, D: ?Sized> Trait<U, V, D> for A<T> +where + T: IncompleteGuidance<U, V>, + A<T>: Trait<U, D, V>, + B<T>: Trait<U, V, D>, + (): ToU8<D>, +{ +} + +trait ToU8<T: ?Sized> {} +impl ToU8<u8> for () {} + +impl<T: ?Sized, U: ?Sized, V: ?Sized, D: ?Sized> Trait<U, V, D> for B<T> +where + T: ImplGuidance<U, V>, + A<T>: Trait<U, V, D>, +{ +} + +fn impls_trait<T: ?Sized + Trait<U, V, D>, U: ?Sized, V: ?Sized, D: ?Sized>() {} + +fn with_bound<X>() +where + X: IncompleteGuidance<i32, u8>, + X: IncompleteGuidance<u32, i8>, + X: IncompleteGuidance<u32, i16>, +{ + impls_trait::<B<X>, _, _, _>(); // entering the cycle from `B` works + + // entering the cycle from `A` fails, but would work if we were to use the cache + // result of `B<X>`. + impls_trait::<A<X>, _, _, _>(); + //~^ ERROR the trait bound `A<X>: Trait<_, _, _>` is not satisfied +} + +fn main() { + with_bound::<u32>(); +} diff --git a/tests/ui/traits/new-solver/coinduction/incompleteness-unstable-result.stderr b/tests/ui/traits/new-solver/coinduction/incompleteness-unstable-result.stderr new file mode 100644 index 00000000000..f1871ff0564 --- /dev/null +++ b/tests/ui/traits/new-solver/coinduction/incompleteness-unstable-result.stderr @@ -0,0 +1,16 @@ +error[E0277]: the trait bound `A<X>: Trait<_, _, _>` is not satisfied + --> $DIR/incompleteness-unstable-result.rs:63:19 + | +LL | impls_trait::<A<X>, _, _, _>(); + | ^^^^ the trait `Trait<_, _, _>` is not implemented for `A<X>` + | + = help: the trait `Trait<U, V, D>` is implemented for `A<T>` +note: required by a bound in `impls_trait` + --> $DIR/incompleteness-unstable-result.rs:51:28 + | +LL | fn impls_trait<T: ?Sized + Trait<U, V, D>, U: ?Sized, V: ?Sized, D: ?Sized>() {} + | ^^^^^^^^^^^^^^ required by this bound in `impls_trait` + +error: aborting due to previous error + +For more information about this error, try `rustc --explain E0277`. diff --git a/tests/ui/traits/new-solver/dont-coerce-infer-to-dyn.rs b/tests/ui/traits/new-solver/dont-coerce-infer-to-dyn.rs new file mode 100644 index 00000000000..c2ac80459ca --- /dev/null +++ b/tests/ui/traits/new-solver/dont-coerce-infer-to-dyn.rs @@ -0,0 +1,17 @@ +// compile-flags: -Ztrait-solver=next +// check-pass + +use std::fmt::Display; +use std::rc::Rc; + +fn mk<T: ?Sized>(t: Option<&T>) -> Rc<T> { + todo!() +} + +fn main() { + let mut x = None; + let y = mk(x); + // Don't treat the line below as a unsize coercion `Rc<?0> ~> Rc<dyn Display>` + let z: Rc<dyn Display> = y; + x = Some(&1 as &dyn Display); +} diff --git a/tests/ui/traits/new-solver/overflow/global-cache.rs b/tests/ui/traits/new-solver/overflow/global-cache.rs new file mode 100644 index 00000000000..adc03da04a8 --- /dev/null +++ b/tests/ui/traits/new-solver/overflow/global-cache.rs @@ -0,0 +1,23 @@ +// compile-flags: -Ztrait-solver=next + +// Check that we consider the reached depth of global cache +// entries when detecting overflow.
