Crate diaryx_extism 

Extism-based third-party plugin runtime for Diaryx.

Loads WebAssembly plugin modules via the Extism runtime and adapts them to the diaryx_core [Plugin], [WorkspacePlugin], and [FilePlugin] traits. Guest plugins communicate with the host through a JSON protocol defined in protocol.

Usage

use diaryx_extism::{HostContext, load_plugins_from_dir};
use std::sync::Arc;

let host_ctx = Arc::new(HostContext { fs: my_async_fs.clone() });
let plugins = load_plugins_from_dir(&plugins_dir, host_ctx)?;
for plugin in plugins {
    let arc = Arc::new(plugin);
    registry.register_workspace_plugin(arc.clone());
    registry.register_file_plugin(arc);
}
