Check if Resumable Run Exists

Source: R/resume.R
can_resume.Rd

Checks whether a valid checkpoint exists that can be resumed. A run can be resumed if:

  • Both run_manifest.json and latest.json exist

  • latest.json points to a valid checkpoint_id

  • The referenced checkpoint can be read and validated

Usage

can_resume(result_path)

Arguments

result_path

Character; path to results directory containing checkpoints.

Value

TRUE if a valid run can be resumed, FALSE otherwise.

Details

This is a cheap existence/validity probe: the checkpoint is validated (checksums, ledger, shard integrity) with load_outcomes = FALSE, so the full outcome history is never deserialized here. Callers that need the outcomes use load_for_resume() instead.
