Needs proper handling instead of unwrap()
let post_id = post_id.ok_or_else(|| {
anyhow!("Post ID should be provided for user streams with source 'post_replies'")
})?;
let author_id = author_id.ok_or_else(|| {
anyhow!("Author ID should be provided for user streams with source 'post_replies'")

Avoid unwrap()
Untested, maybe something like.
let unique_user_ids: HashSet<String> = replies
.map(|replies_batch| {
replies_batch
.into_iter()
.filter_map(|(raw_id, _some_other_data)| {
// Split on ":" and take the first piece; avoid `unwrap()`
raw_id.split(':').next().map(ToString::to_string)
})
.collect::<Vec<String>>()
})
.flatten()
.collect();

Too much logic inside of this arm of the match statement.
We should do the same as for the UserStreamSource::Recommended arm. Move the logic to a new get_post_replies_ids(post_id: &str, author_id: &str) -> Result<Option<Vec<String>>, DynError> function.
