Description
Edit: added reproducible example
Code
This is a minimal (i think) example of a crate that makes Cargo panic.
lib.rs:
mod inner {
pub struct conflict;
impl conflict {
pub fn do_stuff(&self) {}
}
}
mod conflict {}
pub use inner::*;examples/example.rs
fn main() {
dioxus::conflict.do_stuff();
}Test or run the example to get the panic:
# cargo panics:
cargo test
# or
cargo run --example example
Meta
Reproduced on both stable and nightly. I'm on linux but CI tells me this also occurs on Windows and MacOS.
