Struct WasmPluginRuntime 

pub struct WasmPluginRuntime { /* private fields */ }

WASM plugin runtime

Implementations

impl WasmPluginRuntime

pub fn new(config: &PluginRuntimeConfig) -> Result<Self, PluginError>

Create a new WASM runtime

pub fn kv(&self) -> &KvBackend

Expose the per-plugin KV backend so admin/test code can seed or inspect a plugin’s state without going through WASM.

pub fn config(&self) -> &PluginRuntimeConfig

Expose the runtime config so the plugin manager can consult fields it owns (e.g. trust_root) without holding a separate copy.

pub fn instantiate( &self, manifest: &PluginManifest, wasm_bytes: &[u8], ) -> Result<LoadedPlugin, PluginError>

Instantiate a plugin from manifest and WASM bytes

pub fn call_hook( &self, plugin: &LoadedPlugin, hook: HookType, args: &[u8], ) -> Result<Vec<u8>, PluginError>

Call a hook on a plugin via wasmtime.

1. Build a fresh Store (wasmtime stores are not Sync, so each invocation is isolated).
2. Apply fuel metering (per-call fuel cap) when configured.
3. Instantiate the module against an empty Linker — host functions are TODO; plugins that import them will fail at instantiation with a clear error message.
4. Look up memory, alloc, dealloc, and the named hook function exports.
5. Allocate a slot in plugin memory, write args, call the hook, decode (result_ptr, result_len), copy the result bytes out.
6. Free both input and output slots via dealloc.
7. Drop the store; the plugin’s per-call state is gone.

pub fn call_pre_query( &self, plugin: &LoadedPlugin, ctx: &QueryContext, ) -> Result<PreQueryResult, PluginError>

Call pre-query hook

pub fn call_authenticate( &self, plugin: &LoadedPlugin, request: &AuthRequest, ) -> Result<AuthResult, PluginError>

Call authenticate hook

pub fn call_route( &self, plugin: &LoadedPlugin, ctx: &QueryContext, ) -> Result<RouteResult, PluginError>

Call route hook

pub fn stats(&self) -> RuntimeStats

Get runtime statistics
