Struct StoreContextMut

pub struct StoreContextMut<'a, T: 'static>(/* private fields */);

Newtype wrapper around [wasmtime::StoreContextMut<'a, T>].

Implementations

impl<'a, T: 'static> StoreContextMut<'a, T>

pub fn new(inner: StoreContextMut<'a, T>) -> Self

Create a wasm_runtime_layer::StoreContextMut-compatible StoreContextMut from a [wasmtime::StoreContextMut<'a, T>].

pub fn into_inner(self) -> StoreContextMut<'a, T>

Consume a StoreContextMut to obtain the inner [wasmtime::StoreContextMut<'a, T>].

Methods from Deref<Target = StoreContextMut<'a, T>>

pub fn data(&self) -> &T

Access the underlying data owned by this Store.

Same as Store::data.

pub fn data_mut(&mut self) -> &mut T

Access the underlying data owned by this Store.

Same as Store::data_mut.

pub fn engine(&self) -> &Engine

Returns the underlying Engine this store is connected to.

pub fn gc(&mut self, why: Option<&GcHeapOutOfMemory<()>>)

Perform garbage collection of ExternRefs.

Same as Store::gc.

This method is only available when the gc Cargo feature is enabled.

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

Returns remaining fuel in this store.

For more information see Store::get_fuel

pub fn set_fuel(&mut self, fuel: u64) -> Result<(), Error>

Set the amount of fuel in this store.

For more information see Store::set_fuel

pub fn fuel_async_yield_interval( &mut self, interval: Option<u64>, ) -> Result<(), Error>

Configures this Store to periodically yield while executing futures.

For more information see Store::fuel_async_yield_interval

pub fn set_epoch_deadline(&mut self, ticks_beyond_current: u64)

Sets the epoch deadline to a certain number of ticks in the future.

For more information see Store::set_epoch_deadline.

pub fn epoch_deadline_trap(&mut self)

Configures epoch-deadline expiration to trap.

For more information see Store::epoch_deadline_trap.
