Struct wasm_runtime_layer::StoreContextMut

source · 
pub struct StoreContextMut<'a, T: 'a, E: WasmEngine> {
    pub inner: E::StoreContextMut<'a, T>,
}
Expand description

A temporary handle to a &mut Store<T>.

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

Fields§

§inner: E::StoreContextMut<'a, T>

The backing implementation.

Implementations§

source§

impl<'a, T: 'a, E: WasmEngine> StoreContextMut<'a, T, E>

source

pub fn engine(&self) -> &Engine<E>

Returns the underlying Engine this store is connected to.

source

pub fn data(&self) -> &T

Access the underlying data owned by this store.

Same as Store::data.

source

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

Access the underlying data owned by this store.

Same as Store::data_mut.
