Module subvolume_run 

The state a migration command carries between its steps. What: The state one migration command carries between its steps: the platform, the paths, the journal, the progress sink, the list of files this user may not read, and the helper that runs one tree pass and reports it. Why: The migrate, rollback and remove-old commands share it, so each pass is timed, counted and reported the same way and the unreadable-file list is written the same way after every pass (a kill between passes loses nothing).

In TS you’d write (pseudocode):

class Run { platform; layout; journal; interrupt; say(line); async pass(label, source, destination, options) { ... } }

Structs

Run

What: One command’s working state. &'a mut dyn FnMut(&str) is a borrowed progress callback that receives one line at a time. Why: See the module description.

Constants

INDEX_LOCK

The path, relative to a checkout, of the lock the migration holds during its last pass.
