Expand description

Runtime components used when running WebAssembly programs.

Think of this as the “System” in “WebAssembly Systems Interface”.

Required Methods§

source

fn networking(&self) -> &DynVirtualNetworking

Provides access to all the networking related functions such as sockets.

source

fn task_manager(&self) -> &Arc<dyn VirtualTaskManager>

Retrieve the active VirtualTaskManager.

source

fn source(&self) -> Arc<dyn Source + Send + Sync>

The package registry.

Provided Methods§

source

fn package_loader(&self) -> Arc<dyn PackageLoader + Send + Sync>

A package loader.

source

fn module_cache(&self) -> Arc<dyn ModuleCache + Send + Sync>

A cache for compiled modules.

source

fn engine(&self) -> Engine

Get a [wasmer::Engine] for module compilation.

source

fn new_store(&self) -> Store

Create a new wasmer::Store.

source

fn http_client(&self) -> Option<&DynHttpClient>

Get a custom HTTP client

source

fn tty(&self) -> Option<&(dyn TtyBridge + Send + Sync)>

Get access to the TTY used by the environment.

source

fn load_module<'a>( &'a self, wasm: &'a [u8], ) -> BoxFuture<'a, Result<Module, SpawnError>>

Load a a Webassembly module, trying to use a pre-compiled version if possible.

source

fn load_module_sync(&self, wasm: &[u8]) -> Result<Module, SpawnError>

Load a a Webassembly module, trying to use a pre-compiled version if possible.

Non-async version of Self::load_module.

source

fn on_taint(&self, _reason: TaintReason)

Callback thats invokes whenever the instance is tainted, tainting can occur for multiple reasons however the most common is a panic within the process

source

fn journals(&self) -> &Vec<Arc<DynJournal>>

The list of journals which will be used to restore the state of the runtime at a particular point in time

source

fn active_journal(&self) -> Option<&DynJournal>

The snapshot capturer takes and restores snapshots of the WASM process at specific points in time by reading and writing log entries
