Module kv

Interface for Key-Value (KV) Stores

The KV store implementation in Tock has two levels:

1. KV Level: This level provides a standard key-value interface with common get/set/add/update/delete operations.

2. KV Permissions Level: This level mirrors the KV interface, but each call requires storage permissions. This permits implementing access control permissions with key-value stores in Tock.

The expected setup inside Tock will look like this:

+-----------------------+
|  Capsule using K-V    |
+-----------------------+

   hil::kv::KVPermissions (this file)

+-----------------------+
|  K-V in Tock          |
+-----------------------+

   hil::kv::KV (this file)

+-----------------------+
|  K-V library          |
+-----------------------+
