Struct kanidmd_lib::entry::Entry

source ·
pub struct Entry<VALID, STATE> { /* private fields */ }
Expand description

Entry is the core data storage type of the server. Almost every aspect of the server is designed to read, handle and manipulate entries.

Entries store attribute value assertions, or AVA. These are sets of key-values.

Entries have a lifecycle within a single operation, and as part of replication. The lifecycle for operations is defined through state and valid types. Each entry has a pair Of these types at anytime. The first is the AVA schema and access control assertion state. This is represented by the type VALID as one of EntryValid, EntryInvalid or EntryReduced. Every entry starts as EntryInvalid, and when checked by the schema for correctness, transitions to EntryValid. While an entry is EntryValid it can not be altered - you must invalidate it to EntryInvalid, then modify, then check again. An entry that has had access controls applied moves from EntryValid to EntryReduced, to show that the AVAs have reduced to the valid read set of the current event user.

The second type of STATE represents the database commit state and internal db ID’s. A new entry that has never been committed is EntryNew, but an entry that has been retrieved from the database is EntryCommitted. This affects the operations you can apply IE modify or delete.

These types exist to prevent at compile time, mishandling of Entries, to ensure they are always handled with the correct lifecycles and processes.
