Struct wasmer::Store

pub struct Store { /* 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), in addition to the Tunables (that are used to create the memories, tables and globals).

Implementations

impl Store

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

Creates a new Store with a specific Engine.

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

👎Deprecated since 3.0.0: Store::new_with_engine has been deprecated in favor of Store::new

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 new_with_tunables(
    engine: impl Into<Engine>,
    tunables: impl Tunables + Send + Sync + 'static
) -> Self

Creates a new Store with a specific Engine and Tunables.

pub fn tunables(&self) -> &dyn Tunables

Returns the Tunables.

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. The tunables are excluded from the logic.

Trait Implementations

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 TrapHandler for Store

fn custom_trap_handler(&self, call: &dyn Fn(&TrapHandlerFn<'_>) -> bool) -> bool

Uses call to call a custom signal handler, if one is specified.

impl Send for Store

impl Sync for Store
