[−][src]Module terminus_store::storage
Logic for dealing with various storage backends.
Storage in terminus-store is set up in a generic way. Many data
structures simply rely on something that implements FileLoad and
FileStore, leaving the details of retrieval and storage to the
implementer.
Two mechanisms are provided in this library:
- a memory backend
- a file backend
Terminus-store stores databases as part of 2 data structures: a layer store and a label store.
A layer store is a set of directories (though it is up to a specific implementation whether or not this is actually a directory on a filesystem or some other mechanism). Each directory is given a unique name of 20 bytes in hexadecimal format, and stores the layer's primitive data structures as files inside that directory.
A label store is a set of files. The file name is of the format
foo.label, for database foo. This file contains the name of
the layer this label is pointing at.
