Struct WasmExtensionManager 

pub struct WasmExtensionManager { /* private fields */ }

Manages WASM extensions: discovery, loading, and tool execution.

Thread Safety

plugins is wrapped in Arc<Mutex<>> for exclusive thread-safe access. All host functions run inside spawn_blocking, so WASM execution never blocks the async runtime.

Implementations

impl WasmExtensionManager

pub fn new() -> Self

Create an empty manager.

pub fn with_http_client(client: Client) -> Self

Create with a custom HTTP client (useful for testing with a mock client).

pub fn discover(cwd: &Path) -> Vec<PathBuf>

Discover .wasm files in the canonical extensions directory (with legacy read-only fallback) and project-local directories.

pub fn load(&mut self, path: &Path) -> Result<ExtensionInfo>

Load a single .wasm extension.

pub fn load_all( &mut self, paths: &[PathBuf], ) -> (Vec<ExtensionInfo>, Vec<Error>)

Load all discovered extensions, collecting errors.

pub fn execute_tool(&self, tool_name: &str, params: Value) -> Result<Value>

Execute a tool via the WASM extension.

pub fn all_tool_defs(&self) -> Vec<&WasmToolDef>

Get all tool definitions from all loaded extensions.

pub fn is_wasm_tool(&self, tool_name: &str) -> bool

Check if a tool name belongs to a WASM extension.

pub fn extension_names(&self) -> impl Iterator<Item = &str>

List loaded extension names.

pub fn get_info(&self, name: &str) -> Option<&ExtensionInfo>

Get extension info by name.

pub fn len(&self) -> usize

Number of loaded extensions.

pub fn is_empty(&self) -> bool

Whether any extensions are loaded.

pub fn all_command_defs(&self) -> Vec<(&str, &WasmCommandDef)>

Get all command definitions from all loaded extensions.

pub fn execute_command(&self, command_name: &str, args: &str) -> Result<String>

Execute a command via the WASM extension. Returns the output text to display to the user.

impl Default for WasmExtensionManager

fn default() -> Self
