Implementations

impl WasmPackageHost

pub fn new(load_infos: &[PackageLoadInfo], host_state: WasmHostState) -> Self

Load all WASM packages with shared host state.

pub fn call_isolated( &self, package_name: &str, func: &str, input: &str, ) -> Result<String>

pub fn load_package(&mut self, info: &PackageLoadInfo) -> Result<()>

Dynamically load a single plugin. Calls init() after loading.

pub fn unload_package(&mut self, name: &str) -> Result<()>

Unload a package by name. The WASM resources are freed on drop.

pub fn reload_package(&mut self, info: &PackageLoadInfo) -> Result<()>

Reload a plugin: unload then load from the same path.

pub fn call( &self, package_name: &str, func: &str, input: &str, ) -> Result<String>

Call an exported function on a named plugin.

pub fn has_package(&self, name: &str) -> bool

Check if a package is loaded.

pub fn package_names(&self) -> Vec<String>

List loaded package names.

pub fn kv_set(&self, key: &str, value: &str)

Write a value into the shared KV store (same store WASM packages read via host_kv_get). Lets the API layer push runtime state (e.g. team:role_routing on scene activation) without going through a WASM call.

pub fn kv_get(&self, key: &str) -> Option<String>

Read a value from the shared KV store.

pub fn set_app_state(&mut self, app_state: AppState)
