pub async fn list_folder<T: AsyncRead + AsyncWrite + Unpin>(
client: &mut MapClient<T>,
folder: Folder,
) -> Result<Vec<MessageEntry>>Expand description
Lists folder, paging at 1024 entries per request and accumulating across pages.
Listing only — no bodies are fetched, so this is cheap relative to fetch_folder and is
what the live threads aggregation uses. Pure device read: no store access. Returns entries
in device listing order.
§Errors
Returns an error if any MAP set_folder/list_messages operation fails.
