Struct Runtime 

pub struct Runtime { /* private fields */ }

Composable Runtime for invoking Wasm Components

Implementations

impl Runtime

pub fn builder() -> RuntimeBuilder

Create a RuntimeBuilder

pub fn list_components(&self) -> Vec<Component>

List all components

pub fn get_component(&self, name: &str) -> Option<Component>

Get a specific component by name

pub async fn invoke( &self, component_name: &str, function_name: &str, args: Vec<Value>, ) -> Result<Value>

Invoke a component function

pub async fn invoke_with_env( &self, component_name: &str, function_name: &str, args: Vec<Value>, env_vars: &[(&str, &str)], ) -> Result<Value>

Invoke a component function with environment variables

pub async fn instantiate( &self, component_name: &str, ) -> Result<(Store<ComponentState>, Instance)>

Instantiate a component

pub async fn instantiate_with_env( &self, component_name: &str, env_vars: &[(&str, &str)], ) -> Result<(Store<ComponentState>, Instance)>

Instantiate a component with environment variables

pub fn invoker(&self) -> Arc<dyn ComponentInvoker>

Get a component invoker for this runtime.

pub fn publisher(&self) -> Arc<dyn MessagePublisher>

Get a message publisher for this runtime (messaging feature only).

pub fn start(&self) -> Result<()>

Start the runtime (services, in registration order).

Injects dependencies (set_invoker, set_publisher) into each service before calling start().

pub async fn shutdown(&self)

Shutdown all services in reverse registration order.

pub async fn run(&self) -> Result<()>

Start the runtime and block until a shutdown signal (SIGINT/SIGTERM).

Intended for long-lived processes (composable run). For one-off invocations, use start() / shutdown().await directly.
