Struct wasmtime::Store

pub struct Store { /* fields omitted */ }

A Store is a shared cache of information between WebAssembly modules.

Each Module is compiled into a Store and a Store is associated with an Engine. You'll use a Store to attach to a number of global items in the production of various items for wasm modules.

Stores and Clone

Using clone on a Store is a cheap operation. It will not create an entirely new store, but rather just a new reference to the existing object. In other words it's a shallow copy, not a deep copy.

Stores and Default

You can create a store with default configuration settings using Store::default(). This will create a brand new Engine with default ocnfiguration (see Config for more information).

Methods

impl Store

pub fn new(engine: &Engine) -> Store

Creates a new store to be associated with the given Engine.

pub fn engine(&self) -> &Engine

Returns the Engine that this store is associated with.

pub fn same(a: &Store, b: &Store) -> bool

Returns whether the stores a and b refer to the same underlying Store.

Because the Store type is reference counted multiple clones may point to the same underlying storage, and this method can be used to determine whether two stores are indeed the same.

Trait Implementations

impl Clone for Store

fn clone(&self) -> Store

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for Store

fn default() -> Store

Returns the "default value" for a type.
