pub(crate) fn pane_history_tail(
filestore: Option<&FileStore>,
mstore: Option<&Store>,
block_id: &str,
max_bytes: i64,
) -> Option<(Vec<u8>, bool)>Expand description
The last max_bytes of the history a pane renders: its own transcript,
else the agent’s global zone. The bool is whether the window starts
partway into the file (so its first line is a fragment).
