Struct wasmer::Store

pub struct Store { /* fields omitted */ }

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<E: ?Sized>(engine: &E) -> Self where
    E: Engine, 

Creates a new Store with a specific Engine.

pub fn new_with_tunables<E: ?Sized>(
    engine: &E,
    tunables: impl Tunables + Send + Sync + 'static
) -> Self where
    E: Engine, 

Creates a new Store with a specific Engine and Tunables.

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

Returns the Tunables.

pub fn engine(&self) -> &Arc<dyn Engine + Send + Sync>

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 Clone for Store

fn clone(&self) -> Store

Returns a copy of the value.

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

Performs copy-assignment from source.

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 ==.

#[must_use]pub fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
