Questioning lifecycle

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.


Arguments passed on to the restart function. These dots support tidy dots features.

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.
