Struct wasmtime::StoreContext

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

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
