Error message

isto não é um post: cole o link de uma thread (com /comments/ no meio)

What it means

After optional short-link resolution, resolve_post() matches the parsed Target. Only Target::Post is accepted; any other recognized Reddit target (subreddit, user, etc.) hits the wildcard arm and raises this error telling the user to supply a thread link containing /comments/.

Solutions

1. Provide the post permalink containing /comments/ in the path
2. Remove any /comment/<id> suffix and use the parent post URL
3. Use the raw post id instead of a subreddit or user link
4. If the URL is a short link, confirm it redirects to a /comments/ URL, not a subreddit

Example fix

// before
resolve_post(&fetcher, "https://www.reddit.com/r/rust/").await?; // subreddit -> error
// after
resolve_post(&fetcher, "https://www.reddit.com/r/rust/comments/1abcxyz/title/").await?

fn looks_like_thread_url(u: &str) -> bool {
    u.contains("reddit.com") && u.contains("/comments/")
}
if !looks_like_thread_url(input) && !(input.len() >= 5 && !input.contains('/')) {
    eprintln!("input is not a thread link; expected /comments/ URL or post id");
}

fn is_post_input(s: &str) -> bool {
    s.contains("/comments/") || s.starts_with("https://redd.it/") || (s.len() <= 10 && !s.contains('/'))
}

match resolve_post(&fetcher, input).await {
    Ok((id, sub)) => download(id, sub).await,
    Err(e) if e.to_string().contains("nao e um post") => {
        eprintln!("{} is not a thread; need a /comments/ URL", input);
    }
    Err(e) => return Err(e),
}

When it happens

Trigger: Calling resolve_post (via run) with a URL/id that parses to a non-post Reddit target — e.g. a subreddit link (r/example), a user page, a comment permalink, or a gallery/collection link.

Common situations: Users paste a subreddit or user URL when asked for a thread; they paste a link to a comment rather than the post; they paste a crosspost or gallery landing page that parse_target classifies as something other than Post.

Understand the failure class

Background: "is not a compatible type" / "cannot merge" errors: when a value's type doesn't match what the library requires — this error's family across 65 libraries.
