SIGSEGV with nightly when deserializing object about nvim-oxi HOT 3 CLOSED

Hey thanks for the feedback. I don't think it's related to serde, I can replicate the issue simply with

use nvim_oxi::{self as oxi, Dictionary, Function, Object, Result};

// Passing a table here causes a segfault.
fn setup(_: Object) -> Result<()> {
    Ok(())
}

#[oxi::module]
fn foobar() -> Result<Dictionary> {
    Ok(Dictionary::from_iter([("setup", Function::from_fn(setup))]))
}

I have an idea about what could be causing this but I'll look into it.

This should be fixed in f08099d. There is one gotcha however: an empty table will be deserialized as an array instead of a dictionary:

require("foobar").setup({}) -- <- gives error

a possible workaround is to implement Deserialize for Config by hand, implementing the Visitor::visit_seq method on your visitor to check if the sequence is empty.

Thanks @noib3!
