Struct wasmer::Store

pub struct Store {
    pub(crate) inner: Box<StoreInner>,
}

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).

Spec: https://webassembly.github.io/spec/core/exec/runtime.html#store

Fields

inner: Box<StoreInner>

Implementations

impl Store

pub fn new(engine: impl Into<Engine>) -> Self

Creates a new Store with a specific Engine.

pub fn set_trap_handler(&mut self, handler: Option<Box<TrapHandlerFn<'static>>>)

Set the trap handler in this store.

pub fn engine(&self) -> &Engine

Returns the Engine.

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

Checks whether two stores are identical. A store is considered equal to another store if both have the same engine.

pub fn id(&self) -> StoreId

Returns the ID of this store

Trait Implementations

impl AsEngineRef for Store

fn as_engine_ref(&self) -> EngineRef<'_>

Returns a EngineRef pointing to the underlying context.

impl AsStoreMut for Store

fn as_store_mut(&mut self) -> StoreMut<'_>

Returns a StoreMut pointing to the underlying context.

fn objects_mut(&mut self) -> &mut StoreObjects

Returns the ObjectMutable

impl AsStoreRef for Store

fn as_store_ref(&self) -> StoreRef<'_>

Returns a StoreRef pointing to the underlying context.

impl Debug for Store

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Store

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq<Store> for Store

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Send for Store

impl Sync for Store
