Struct sc_executor::sandbox::Store[][src]

pub struct Store<DT> { /* fields omitted */ }
Expand description

This struct keeps track of all sandboxed components.

This is generic over a supervisor function reference type.

Implementations

Create a new empty sandbox store.

Create a new memory instance and return it’s index.

Errors

Returns Err if the memory couldn’t be created. Typically happens if initial is more than maximum.

Returns SandboxInstance by instance_idx.

Errors

Returns Err If instance_idx isn’t a valid index of an instance or instance is already torndown.

Returns dispatch thunk by instance_idx.

Errors

Returns Err If instance_idx isn’t a valid index of an instance or instance is already torndown.

Returns reference to a memory instance by memory_idx.

Errors

Returns Err If memory_idx isn’t a valid index of an memory or if memory has been torn down.

Tear down the memory at the specified index.

Errors

Returns Err if memory_idx isn’t a valid index of an memory or if it has been torn down.

Tear down the instance at the specified index.

Errors

Returns Err if instance_idx isn’t a valid index of an instance or if it has been torn down.

Instantiate a guest module and return it’s index in the store.

The guest module’s code is specified in wasm. Environment that will be available to guest module is specified in guest_env. A dispatch thunk is used as function that handle calls from guests. state is an opaque pointer to caller’s arbitrary context normally created by sp_sandbox::Instance primitive.

Note: Due to borrowing constraints dispatch thunk is now propagated using DTH

Returns uninitialized sandboxed module instance or an instantiation error.
