Module transfer 

Shared planning and execution primitives for bulk transfers.

Commands expand their own storage-specific inputs into TransferCandidate values, then use this module for consistent selection, ordering, retry, rate, concurrency, cancellation, and aggregate summary behavior.

Structs

TransferCancellation

Cooperative cancellation shared by a transfer command and its executor.

TransferCandidate

A storage-independent item that can be selected and executed as part of a transfer.

TransferControls

Controls applied across the entire transfer command.

TransferExecutor

Executes a transfer plan with shared controls.

TransferOutcome

Deterministically ordered result for one candidate.

TransferPlan

Selected candidates in deterministic execution and output order.

TransferReport

Aggregate execution result and per-candidate outcomes.

TransferSelection

Shared path and UTC timestamp selection rules.

TransferSummary

Deterministic aggregate counters for a transfer plan and its execution.

Enums

TransferOutcomeState

Result state for one candidate.
