Autocomplete std::fs::ReadDir in a loop

[ANtlord]

Hello! I've got such piece of code.

use std::path;
fn main() {
    let tmp_dir_path = path::Path::new("/tmp");
    let tmp_dir_read = tmp_dir_path.read_dir().unwrap();
    for dir_entry in tmp_dir_read {
        dir_entry.//stay here
    }
}

RLS doesn't suggest fields of io::Result<DirEntry> in a loop only. I got such issue a couple of times with other structures but I've fixed it on a ReadDir instance. If you try to create another structure and implementer Iterator for it so RLS works perfect with it.

Is it bug or did I miss something in configuration?

Similar issue with vectors.

fn main() -> std::io::Result<()> {
    let v = vec![vec![1, 2, 3], vec![1, 2, 3]];

    for iv in v {
        let s = iv;
        s. // Autocomplete doesn't work
    }

    Ok(())
}

fn main() -> std::io::Result<()> {
    let v = vec![vec![1, 2, 3], vec![1, 2, 3]];

    for iv in v {
        let s: Vec<i32> = iv;
        s. // Autocomplete works
    }

    Ok(())
}
