Struct 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<T> StoreContext<'_, T>

pub fn engine(&self) -> &Engine

Returns the underlying Engine this store is connected to.

pub fn data(&self) -> &T

Access the underlying data owned by this store.

Same as Store::data.

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

Returns the remaining fuel of the Store if fuel metering is enabled.

For more information see Store::get_fuel.

Errors

If fuel metering is disabled.
