Struct Engine 

pub struct Engine { /* private fields */ }

A compiled-code and runtime environment, shared across Stores and threads.

Cheap to clone (reference-counted handle), Send + Sync — mirrors wasmtime::Engine.

Implementations

impl Engine

pub fn new(config: &Config) -> Result<Engine>

Creates a new Engine from the given configuration.

pub fn precompile_module(&self, bytes: &[u8]) -> Result<Vec<u8>>

Compiles bytes and returns the serialized compiled artifact (as [Module::serialize]), suitable for unsafe Module::deserialize. Validates + compiles once here so deserialize can skip both.

pub fn increment_epoch(&self)

Bumps the epoch counter; pairs with Store::set_epoch_deadline.

pub fn weak(&self) -> EngineWeak

Returns a non-owning handle to this engine (e.g. for an epoch ticker thread).
