Reduced: 

#![feature(generic_const_exprs)]
impl<const N: usize> Encodable for IntX<N> {
    const E: usize = 32;
    fn encode()
    where
        [(); Self::E]:,
    {
    }
}

pub trait Encodable {
    const E: usize;

    fn encode()
    where
        [(); Self::E]:;
}

pub struct IntX<const N: usize>;

and main.rs:

use syslib::{Encodable, IntX};

fn main() {
    IntX::<32>::encode();
}

This looks a lot like a duplicate of #128525.
