# waSCC Codec
The _WebAssembly Secure Capabilities Connector_ (waSCC) codec library contains a set of types and other primitives that are common to the host runtime, capability providers, and actor modules that are created for use with the [wascc](https://wasc.dev) host runtime, which is in turn built on top of [WebAssembly Procedure Call (waPC)](https://github.com/wapc) primitives.
These types are serializable and de-serializable into a binary format using _[message pack](https://msgpack.org)_. This format consumes a bit more space on the wire than protocol buffers, but imposes less boilerplate burden on developers and produces significantly less latency during serialization/de-serialization.
This crate includes definitions for a standard set of operations supported by the default capability providers:
* **Messaging** - Message broker functionality (pub, sub, request)
* **HTTP Server** - HTTP server capability
* **HTTP Client** - HTTP client capability
* **Key-Value Store** - Standard K/V operations, including lists, sets, and atomic counters
* **Blob Store** - Cloud-native file storage capability
* **Extras** - Random number generation, sequence numbers, etc
* **Streams** - Support for an append-only event stream provider
