Function get_changes_up_to_change

atomic-repository/src/history/operations.rs:349–364

Get all change NodeIds applied up to and including a specific change. This is a convenience wrapper around [`get_changes_up_to_sequence`] that includes the specified change in the result set. # Arguments `txn` - Read transaction `view` - The view to query `change_hash` - Hash of the change to include (and all before it) # Returns `Ok(Some(set))` - Set of changes including the specified change

    txn: &T,
    view: &ViewState,
    change_hash: &Hash,
)

/// * `Ok(None)` - The change is not in this view's history
/// * `Err(_)` - Database error
