Struct spin_core::Store

pub struct Store<T> { /* private fields */ }

A Store holds the runtime state of a Spin instance.

In general, a Store is expected to live only for the lifetime of a single Spin trigger invocation.

A Store can be built with a StoreBuilder.

Implementations

impl<T> Store<T>

pub fn host_components_data(&mut self) -> &mut HostComponentsData

Returns a mutable reference to the HostComponentsData of this Store.

pub fn set_deadline(&mut self, deadline: Instant)

Sets the execution deadline.

This is a rough deadline; an instance will trap some time after this deadline, determined by [EngineBuilder::epoch_tick_interval] and details of the system’s thread scheduler.

See wasmtime::Store::set_epoch_deadline.

Trait Implementations

impl<T> AsContext for Store<T>

type Data = Data<T>

The host information associated with the Store, aka the T in Store<T>.

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

Returns the store context that this type provides access to.

impl<T> AsContextMut for Store<T>

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

Returns the store context that this type provides access to.

impl<T> AsMut<Store<Data<T>>> for Store<T>

fn as_mut(&mut self) -> &mut Store<Data<T>>

Converts this type into a mutable reference of the (usually inferred) input type.

impl<T> AsRef<Store<Data<T>>> for Store<T>

fn as_ref(&self) -> &Store<Data<T>>

Converts this type into a shared reference of the (usually inferred) input type.
