pub fn remove_thread(
db: &Db,
project: &str,
branch: &str,
id: &str,
) -> Result<bool>Expand description
Remove the single thread id from (project, branch), dropping the
row entirely when it was the last one. Returns whether a thread was
removed. Used when the user clears a reopened comment’s text to
delete it, so it doesn’t resurrect on the next hydrate.
