Struct WasmStoreRef

pub struct WasmStoreRef { /* private fields */ }

This representation of a Store is used to implement the wasm.h API (and not the wasmi.h API!)

This is stored alongside Func and such for wasm.h so each object is independently owned. The usage of Arc here is mostly to just get it to be safe to drop across multiple threads, but otherwise acquiring the context values from this struct is considered unsafe due to it being unknown how the aliasing is working on the C side of things.

The aliasing requirements are documented in the C API wasm.h itself (at least Wasmi’s implementation).

Implementations

impl WasmStoreRef

pub unsafe fn context(&self) -> StoreContext<'_, ()>

Returns shared access to the store context of the WasmStoreRef.

Wraps wasmi::AsContext.

Safety

It is the callers responsibility to provide a valid self.

pub unsafe fn context_mut(&mut self) -> StoreContextMut<'_, ()>

Returns mutable access to the store context of the WasmStoreRef.

Wraps wasmi::AsContextMut.

Safety

It is the callers responsibility to provide a valid self.

Trait Implementations

impl Clone for WasmStoreRef

fn clone(&self) -> WasmStoreRef

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
