Provides drop-in replacements for 'purrr' and 'furrr' mapping
functions with built-in fault tolerance, automatic checkpointing, and
seamless recovery capabilities. When long-running computations are
interrupted due to errors, system crashes, or other failures, simply
re-run the same code to automatically resume from the last checkpoint.
Ideal for large-scale data processing, API calls, web scraping, and
other time-intensive operations where reliability is critical. For
'purrr' methodology, see Wickham and Henry (2023)
<https://purrr.tidyverse.org/>.
