headers.keys() does not return an iterator

[nabetti1720]

Currently, LLRT does not pass the following tests:

fetch/api/headers > should pass headers-basic.any.js tests
Error: [Check keys method] assert_equals: expected object "[object Iterator]" but got object "[object Object]"

This is probably because the return value of keys() is of type Vec<&str>.

pub fn keys(&self) -> Vec<&str>

I tried writing impl Iterator<Item = &str>, but an error occurs during build because there is no implementation of IntoJs. I believe this is because this is the way to write it when using an iterator within rust.

Is there any mechanism like the one below on the RquickJS side that I can use to solve the problem?

There is no built in iterator conversion in rquckjs. We should probably build one that makes this a bit more ergonomic.
I added a PR in rquickjs for this:
