Description
While writing some code I wanted to see if it compiled, and instead cargo build just hung, either forever or longer than I was willing to late. It's a bug either way. I think I got it stuck in an infinite loop resolving traits
Code is here. I was editing mask.rs when I encountered the issue.
I think the problem code is
pub trait Maskable<T>: Copy {
type Mask: Mask;
fn set_masked<R: Splat<Self>>(&mut self, mask: Self::Mask, value: R);
}
impl<T, const N: usize> Maskable<T> for Col<T, N>
where
T: Copy,
{
type Mask = Col<bool, N>;
fn set_masked<R: Splat<Self>>(&mut self, mask: Self::Mask, value: R) {
let value: Self = value.splat();
for (i, &m) in mask.iter().enumerate() {
if m {
self[i] = value[i]
}
}
}
}
impl<S: Copy, T: Copy, const H: usize, const W: usize> Maskable<T> for Mat<S, W, H>
where
Col<S, W>: Copy + Maskable<T>,
{
type Mask = Col<Col<S, W>::Mask, H>;
fn set_masked<R: Splat<Self>>(&mut self, mask: Self::Mask, value: R) {
let value: Self = value.splat();
for (i, &m) in mask.iter().enumerate() {
self[i].set_masked(m, value[i]);
}
}
}(this code is bad and wrong but it probably shouldn't do this)
I cant include a backtrace because Cargo never terminates
