Struct wasm_runtime_layer::Store

pub struct Store<T, E: WasmEngine> { /* private fields */ }

The store represents all global state that can be manipulated by WebAssembly programs. It consists of the runtime representation of all instances of functions, tables, memories, and globals that have been allocated during the lifetime of the abstract machine.

The Store holds the engine (that is —amongst many things— used to compile the Wasm bytes into a valid module artifact).

Implementations

impl<T, E: WasmEngine> Store<T, E>

pub fn new(engine: &Engine<E>, data: T) -> Self

Creates a new Store with a specific Engine.

pub fn engine(&self) -> &Engine<E>

Returns the Engine that this store is associated with.

pub fn data(&self) -> &T

Returns a shared reference to the user provided data owned by this Store.

pub fn data_mut(&mut self) -> &mut T

Returns an exclusive reference to the user provided data owned by this Store.

pub fn into_data(self) -> T

Consumes self and returns its user provided data.

Trait Implementations

impl<T, E: WasmEngine> AsContext for Store<T, E>

type Engine = E

The engine type associated with the context.

type UserState = T

The user state associated with the Store, aka the T in Store<T>.

fn as_context(&self) -> StoreContext<'_, Self::UserState, Self::Engine>

Returns the store context that this type provides access to.

impl<T, E: WasmEngine> AsContextMut for Store<T, E>

fn as_context_mut( &mut self ) -> StoreContextMut<'_, Self::UserState, Self::Engine>

Returns the store context that this type provides access to.
