A low-ish level tool for easily hosting WASM based plugins.

The goal of wasm_plugin is to make communicating across the host-plugin boundary as simple and idiomatic as possible while being unopinionated about how you actually use the plugin.

Loading a plugin is as simple as reading the .wasm file off disk.

rust let mut plugin = WasmPlugin::load("path/to/plugin.wasm")?;

Calling functions exported by the plugin takes one of two forms. Either the function takes no arguments and returns a single serde deserializable value:

rust let response: ResultType = plugin.call_function("function_name")?;

Or it takes a single serializable argument and returns a single result:

rust let message = Message::default(); let response: ResultType = plugin.call_function_with_argument("function_name", &message)?;
