An Artifact is the product that the Engine implementation produce and use.

An Artifact is the product that the Engine implementation produce and use.

The ArtifactRun contains the extra information needed to run the module at runtime, such as [ModuleInfo] and [Features].

Required Methods

fn register_frame_info(&self)

Register thie Artifact stack frame information into the global scope.

This is required to ensure that any traps can be properly symbolicated.

fn finished_functions(&self) -> &BoxedSlice<LocalFunctionIndex, FunctionBodyPtr>

Returns the functions allocated in memory or this Artifact ready to be run.

fn finished_function_call_trampolines(
    &self
) -> &BoxedSlice<SignatureIndex, VMTrampoline>

Returns the function call trampolines allocated in memory of this Artifact, ready to be run.

fn finished_dynamic_function_trampolines(
    &self
) -> &BoxedSlice<FunctionIndex, FunctionBodyPtr>

Returns the dynamic function trampolines allocated in memory of this Artifact, ready to be run.

fn signatures(&self) -> &BoxedSlice<SignatureIndex, VMSharedSignatureIndex>

Returns the associated VM signatures for this Artifact.

fn func_data_registry(&self) -> &FuncDataRegistry

Get the func data registry

Provided Methods

fn preinstantiate(&self) -> Result<(), InstantiationError>

Do preinstantiation logic that is executed before instantiating

unsafe fn instantiate(
    &self,
    tunables: &dyn Tunables,
    resolver: &dyn Resolver,
    host_state: Box<dyn Any>
) -> Result<InstanceHandle, InstantiationError>

Crate an Instance from this Artifact.

Safety

See InstanceHandle::new.

unsafe fn finish_instantiation(
    &self,
    trap_handler: &(dyn TrapHandler + 'static),
    handle: &InstanceHandle
) -> Result<(), InstantiationError>

Finishes the instantiation of a just created InstanceHandle.

Safety

See InstanceHandle::finish_instantiation.

Implementations

impl dyn Artifact + 'static

pub fn downcast_ref<T: 'static>(&self) -> Option<&T>

Try to downcast the artifact into a given type.

pub fn downcast_mut<T: 'static>(&mut self) -> Option<&mut T>

Try to downcast the artifact into a given type mutably.
