Bugs when trying to infer type of const generic #88891

Open fishrockz opened 3 years ago

fishrockz commented 3 years ago

I tried using #![feature(generic_arg_infer)]

and got the following crashes, if you want me to push up some commits and link them here i can if it would be useful.

Thanks Will

Code

pub struct ICMCommon<InterfaceThing: ?Sized, E> {
    phantom: PhantomData<InterfaceThing>,
    sleep_bit: BitStruct<dyn Interface<Error = InterfaceError<E>>, _,_,_>,
}

later

    pub fn new() -> Result<Self, BitByteStructError<InterfaceError<E>>> {
        let sleep_bit = BitStruct::<dyn Interface<Error = InterfaceError<E>>, ICM20X_B0_PWR_MGMT_1, 1, 6>::new()?
   }

gives

Could you give us the full source code but at least Bitstruct and it's new function along with all needed types (InterfaceThing, Interface, InterfaceError, ICM20X_B0_PWR_MGMT_1) :)

fishrockz commented 3 years ago

This seems to reproduce nicely.

https://gitlab.com/pointswaves/icm20948-rs/-/tree/rustissue-88891

This is the line that i want to infer the type with:

https://gitlab.com/pointswaves/icm20948-rs/-/blob/rustissue-88891/src/lib.rs#L230

Several of the following lines need ether there type adding explicitly or adding _, _, _ but even so, rustc shouldn't crash like this?

If you do set everything explicitly then the code dose works, https://gitlab.com/pointswaves/icm20948-rs/-/commit/a52c8253a7a63775d3c772f8972725bc562e8139#b24749917179fb5e3e613ed2a703fcdcc6cdf9da_237_231

I also just encountered what I believe to be this issue (same ICE location). I've encountered two separate bugs):

The relevant code for the second (reproducible) error:

str4d commented 2 years ago

I tried to reproduce my second ICE above against several toolchain versions:

So this issue may have been fixed inadvertently, or is a duplicate of another issue that was explicitly fixed in 1.57.0. I have not tried to reproduce OP's ICE in recent toolchain versions.

istankovic commented 1 year ago

Couldn't reproduce this. @fishrockz is this still relevant?

jieyouxu commented 9 months ago

Ping from triage: @fishrockz is this still an issue?
