2 years ago Interesting.
So, the problem here is that the type of FooFuture has some bounds that are required for that type to be constructed (namely B: Bar), but we end up "getting" a variable with that type without satisfying that. Here through zeroed, but can also be done through a function with a todo!() body.

2 years ago Update: the below examples are no longer ICEs.
Some "reductions" that should have the same root cause as described above, although they error slightly differently (they all produce some kind of complaint that u32 is not Bar):
Using closures instead of async:
#![feature(generic_associated_types)]
#![feature(type_alias_impl_trait)]
trait Bar {
fn bar(&self);
}
trait Foo {
type FooFn<B>: FnOnce();
fn foo<B: Bar>(&self, bar: B) -> Self::FooFn<B>;
}
struct MyFoo;
impl Foo for MyFoo {
type FooFn<B> = impl FnOnce();
fn foo<B: Bar>(&self, bar: B) -> Self::FooFn<B> {
move || { bar.bar() }
}
}
fn main() {
let boom: <MyFoo as Foo>::FooFn<u32> = unsafe { core::mem::zeroed() };
boom();
}Using a custom trait instead of Future/FnOnce:
#![feature(generic_associated_types)]
#![feature(type_alias_impl_trait)]
trait Bar {
fn bar(&self);
}
trait Baz {
fn baz(&self);
}
trait Foo {
type FooFn<B>: Baz;
fn foo<B: Bar>(&self, bar: B) -> Self::FooFn<B>;
}
struct MyFoo;
impl Foo for MyFoo {
type FooFn<B> = impl Baz;
fn foo<B: Bar>(&self, bar: B) -> Self::FooFn<B> {
MyBaz(bar)
}
}
struct MyBaz<B: Bar>(B);
impl <B: Bar> Baz for MyBaz<B> {
fn baz(&self) {}
}
fn main() {
let boom: <MyFoo as Foo>::FooFn<u32> = unsafe { core::mem::zeroed() };
boom.baz();
}If you use a non-associated type alias instead of a GAT, the async and FnOnce versions still ICE but the custom trait version doesn't. See #90409

2 years ago GATs issue triage: not blocking. Given that there are similar repros without GATs, this basically confirms my suspicion that this isn't a GAT issue, but a TAIT one.

2 years ago The custom trait version no longer ICEs since #90948, the rest still do

2 years ago Triage: All the examples on the comment (https://github.com/rust-lang/rust/issues/90400#issuecomment-954927836) are no longer ICE, I'm going to mark as E-needs-test.

2 years ago Triage: the original code still triggers an ICE. In https://github.com/rust-lang/rust/pull/97309, I've added some tests based on https://github.com/rust-lang/rust/issues/90400#issuecomment-954927836.
Unmarking this as E-needs-test and marking as E-needs-mcve, so that we can include the original's to glacier.

2 years ago The original doesn't ICE anymore on playground, it reports a few errors, but fixing them produces no ICEs at any stage

commented
6 months ago any reason why this is not closed yet? we do have tests for this inside rustc
Code
I think the cause is the code is incorrect: FooFuture should require
where B: Bar. It doesn't, somehow the compiler doesn't catch this, and then ICEs at codegen if you try to useFooFuture<u32>because u32 is not Bar.playground
