Struct wasmer_vm::store::StoreHandle
source · pub struct StoreHandle<T> {
id: StoreId,
internal: InternalStoreHandle<T>,
}
Expand description
Handle to an object managed by a context.
Internally this is just an integer index into a context. A reference to the context must be passed in separately to access the actual object.
Fields§
§id: StoreId
§internal: InternalStoreHandle<T>
Implementations§
source§impl<T: StoreObject> StoreHandle<T>
impl<T: StoreObject> StoreHandle<T>
sourcepub fn new(ctx: &mut StoreObjects, val: T) -> Self
pub fn new(ctx: &mut StoreObjects, val: T) -> Self
Moves the given object into a context and returns a handle to it.
sourcepub fn get<'a>(&self, ctx: &'a StoreObjects) -> &'a T
pub fn get<'a>(&self, ctx: &'a StoreObjects) -> &'a T
Returns a reference to the object that this handle points to.
sourcepub fn get_mut<'a>(&self, ctx: &'a mut StoreObjects) -> &'a mut T
pub fn get_mut<'a>(&self, ctx: &'a mut StoreObjects) -> &'a mut T
Returns a mutable reference to the object that this handle points to.
sourcepub fn internal_handle(&self) -> InternalStoreHandle<T>
pub fn internal_handle(&self) -> InternalStoreHandle<T>
Returns the internal handle contains within this handle.
sourcepub fn set_store_id(&mut self, id: StoreId)
pub fn set_store_id(&mut self, id: StoreId)
Overrides the store id with a new ID
sourcepub unsafe fn from_internal(
id: StoreId,
internal: InternalStoreHandle<T>,
) -> Self
pub unsafe fn from_internal( id: StoreId, internal: InternalStoreHandle<T>, ) -> Self
Constructs a StoreHandle
from a StoreId
and an InternalStoreHandle
.
§Safety
Handling InternalStoreHandle
values is unsafe because they do not track context ID.
