Restarts are named jumping points established by
rst_list() returns the names of all restarts currently
rst_exists() checks if a given restart is
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_list() rst_exists(.restart) 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.
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.
