Struct StoreContext

pub struct StoreContext<'a, T>(/* private fields */);

Available on crate feature runtime only.

A temporary handle to a &Store<T>.

This type is suitable for AsContext trait bounds on methods if desired. For more information, see Store.

Implementations

impl<'a, T> StoreContext<'a, T>

pub fn engine(&self) -> &Engine

Returns the underlying Engine this store is connected to.

pub fn data(&self) -> &'a T

Access the underlying data owned by this Store.

Same as Store::data.

pub fn get_fuel(&self) -> Result<u64>

Returns the remaining fuel in this store.

For more information see Store::get_fuel.

Trait Implementations

impl<T> AsContext for StoreContext<'_, T>

type Data = T

fn as_context(&self) -> StoreContext<'_, T>

Returns the store context that this type provides access to.

impl<'a, T: AsContext> From<&'a T> for StoreContext<'a, T::Data>

fn from(t: &'a T) -> StoreContext<'a, T::Data>

Converts to this type from the input type.

impl<'a, T: AsContext> From<&'a mut T> for StoreContext<'a, T::Data>

fn from(t: &'a mut T) -> StoreContext<'a, T::Data>

Converts to this type from the input type.

impl<'a, T> From<StoreContextMut<'a, T>> for StoreContext<'a, T>

fn from(store: StoreContextMut<'a, T>) -> StoreContext<'a, T>

impl<I, T> Index<I> for StoreContext<'_, T>

where StoreData: Index<I>,

type Output = <StoreData as Index<I>>::Output
