rst_list: Restarts utilities

Description

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.

Usage

rst_exists(.restart)

rst_jump(.restart, ...)

rst_maybe_jump(.restart, ...)

Arguments

.restart

The name of a restart.

Arguments passed on to the restart function. These dots are evaluated with explicit splicing.
