Crate wasmcloud_actor_keyvalue

wasmCloud Key-Value Store Actor Interface

This crate provides wasmCloud actors with an interface to the key-value capability provider. Actors using this interface must have the claim wasmcloud:keyvalue in order to have permission to communicate with the store.

The key-value provider is one-way, and only accepts host calls from the actor. This provider does not deliver messages to actors.

Example:

extern crate wasmcloud_actor_keyvalue as kv;
use wapc_guest::HandlerResult;

fn add() -> HandlerResult<()> {
  let _ = kv::default().add("test".to_string(), 1)?;    
  Ok(())
}

Functions

default	Creates the default host binding
deserialize	The standard function for de-serializing codec structs from a format suitable for message exchange between actor and host. Use of any other function to deserialize could result in breaking incompatibilities.
host	Creates a named host binding
serialize	The standard function for serializing codec structs into a format that can be used for message exchange between actor and host. Use of any other function to serialize could result in breaking incompatibilities.
