Struct wasmtime::StoreContext

#[repr(transparent)]
pub struct StoreContext<'a, T>(_);

A temporary handle to a &Store<T>.

This type is sutable 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 interrupt_handle(&self) -> Result<InterruptHandle>

Returns an InterruptHandle to interrupt wasm execution.

See Store::interrupt_handle for more information.

pub fn data(&self) -> &T

Access the underlying data owned by this Store.

Same as Store::data.

pub fn fuel_consumed(&self) -> Option<u64>

Returns the fuel consumed by this store.

For more information see Store::fuel_consumed.

Trait Implementations

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

type Data = T
