Confusing error message when trait bound is "satisfied" from different version of same crate

[bugadani]

Hi!

I was trying to make the following extension to heapless in my project:

use heapless::spsc::Consumer;
use heapless::spsc::MultiCore;
use generic_array::ArrayLength;
pub trait ConsumerExt {
    fn flush(&mut self);
}

impl<T, N> ConsumerExt for Consumer<'_, T, N, usize, MultiCore>
where
    N: ArrayLength<T>,
{
    fn flush(&mut self) {
        while self.dequeue().is_some() {}
    }
}

In this case, the compatible type is reexported as heapless::ArrayLength;
I now understand that my generic_array::ArrayLength was from a mismatching version of generic_array. Regardless, the error message is extremely confusing:

error[E0277]: the trait bound `N: generic_array::ArrayLength<T>` is not satisfied

help: consider further restricting this bound
