wasmCloud Extras Actor Interface
This crate provides wasmCloud actors with an interface to the extras capability provider.
Every wasmCloud host runtime automatically comes with a built-in extras provider. However,
actors using this provider will still need to be signed with the wasmcloud:extras
capability contract ID.
The following functions are supported on the extras Host
interface:
Example:
extern crate wapc_guest as guest; use guest::prelude::*; use wasmcloud_actor_core as actor; use wasmcloud_actor_extras as extras; use wasmcloud_actor_http_server as http; use serde_json::json; use log::{error, info}; use extras::{GeneratorResult, GeneratorRequest}; #[actor::init] pub fn init() { http::Handlers::register_handle_request(generate_guid); } /// Generate a Guid and return it in a JSON envelope fn generate_guid(_req: http::Request) -> HandlerResult<http::Response> { let request = GeneratorRequest { guid: true, random: false, sequence: false, min: 0, max: 0 }; let guid = extras::default().request_guid(request)?; let result = json!({"guid": guid }); Ok(http::Response::json(&result, 200, "OK")) }

Functions
Creates the default host binding
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.
Creates a named host binding
