	// TTLFunc returns the TTL (time to live) that objects should be persisted
	// with. The existing parameter is the current TTL or the default for this
	// operation. The update parameter indicates whether this is an operation
	// against an existing object.
	//
	// Objects that are persisted with a TTL are evicted once the TTL expires.

finds any problems, go test reports those and does not run the test
binary. Only a high-confidence subset of the default go vet checks are
used. That subset is: atomic, bool, buildtags, directive, errorsas,
ifaceassert, nilfunc, printf, and stringintconv. You can see
the documentation for these and other vet tests via "go doc cmd/vet".
To disable the running of go vet, use the -vet=off flag. To run all
checks, use the -vet=all flag.
