Restarts are named jumping points established by with_restarts(). rst_list() returns the names of all restarts currently established. rst_exists() checks if a given restart is established. rst_jump() stops execution of the current function and jumps to a restart point. If the restart does not exist, an error is thrown. rst_maybe_jump() first checks that a restart exists before jumping.



rst_jump(.restart, ...)

rst_maybe_jump(.restart, ...)



The name of a restart.


<dynamic> Arguments passed on to the restart function.

Life cycle

All the restart functions are in the questioning stage. It is not clear yet whether we want to recommend restarts as a style of programming in R.
