Module store 

One tenant’s vCons: a sealed object per kept version and a catalog row for it. The catalog is the truth: a version exists once its row is committed, and an object with no row is garbage. Every rule is here; the catalog and the objects are reached through the backend traits.

Structs

Caller

Who is calling, for the audit record.

Copied

What backup_to copied.

Counts

What a tenant’s Store keeps, as removal checks it.

Cursor

Where a page ends: the last listed vCon’s first stored time and uuid. Clients get it as opaque text and send it back unchanged.

Examination

One Store as check found it.

Kept

What the purge rule reads of one version.

KeptVersion

A kept version as the export lists it.

Legal

A version as a legal read returns it, and whether its uuid is deleted.

ListQuery

What a list asks for: at most limit vCons, after cursor, first stored at or after since and before until.

Listed

A live vCon as the list shows it.

Listing

One page of a list, and the cursor of the next one, None on the last.

PurgeReport

What a purge did.

Store

One tenant’s vCons.

Stored

A version as get returns it.

VersionInfo

One kept version of a uuid, as the legal version list shows it.

Enums

BackupError

Why a backup of a Store failed.

Created

What create did.

ExamineError

Why a Store could not be examined.

OpenError

Why a tenant’s Store did not open: kept apart so a key that does not open its catalog is never confused with files this process may not use.

StoreError

Why a Store call was refused or failed.

Constants

TRIES

How many times the catalog is copied while versions in each copy are purged before their object files are copied.

Functions

due

Whether version is due for purge at now under retention: it is hidden, its uuid has no hold, and retention has passed since it was stored, counted in calendar time in UTC. A period that ends past the last time this build can hold never passes. A version hidden after it reached that age is due at once.
