Struct sc_executor::sandbox::Store

pub struct Store<FR> { /* fields omitted */ }

This struct keeps track of all sandboxed components.

This is generic over a supervisor function reference type.

Implementations

impl<FR> Store<FR>

pub fn new() -> Store<FR>

Create a new empty sandbox store.

pub fn new_memory(&mut self, initial: u32, maximum: u32) -> Result<u32, Error>

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.

pub fn instance(
    &self,
    instance_idx: u32
) -> Result<Rc<SandboxInstance<FR>>, Error>

Returns SandboxInstance by instance_idx.

Errors

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

pub fn memory(&self, memory_idx: u32) -> Result<MemoryRef, Error>

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.

pub fn memory_teardown(&mut self, memory_idx: u32) -> Result<(), Error>

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.

pub fn instance_teardown(&mut self, instance_idx: u32) -> Result<(), Error>

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.
