Package dir implements an on-disk reference storage adapter.

package memcached implements a reference store adapter backed by a separate Memcached server.

Package nop implements a no-op reference store adapter.

NewIdentifier calculates the reference ID from the given file contents.

NewStore creates a new reference store with the given DSN and retention policy.

ParseIdentifier takes an input in the form "sha256:...." and transforms it into an Identifier.

ReadIdentifier creates an identifier of the contents read from r.

RegisterAdapter will remember the given adapter with under the given name.

ToIdentifier converts b into the canonical Identifier representation.

ErrInvalidAccessListConfig is returned from NewAccessList when the quota arguments (maxItems and totalSizeQuota) are both <= 0.

ErrUnknownReference can be returned from Adapter implementations, if a given Identifier is unknown to them.

AccessList implements a size- and/or space-limited RetentionPolicy.

FileRef represents a reference file.

KeepForever is a no-op retention policy, i.e.

PurgeOnStart will delete all files when the reference store is instantiated.

The Adapter interface describes the protocol to interact with different storage backends.

A RetentionPolicy describes how various reference store implementations should handle deletion of old references.

AdapterConstructor constructs a new adapter implementation from the given config DSN and retention policy.

File references are identified by their checksum.
