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

The Artifact contains the compiled data for a given module as well as extra information needed to run the module at runtime, such as ModuleInfo and Features.

Required methods

pub fn module(&self) -> Arc<ModuleInfo>[src]

Return a reference-counted pointer to the module

pub fn module_ref(&self) -> &ModuleInfo[src]

Return a pointer to a module.

pub fn module_mut(&mut self) -> Option<&mut ModuleInfo>[src]

Gets a mutable reference to the info.

Note: this will return None if the module is already instantiated.

pub fn register_frame_info(&self)[src]

Register thie Artifact stack frame information into the global scope.

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

pub fn features(&self) -> &Features[src]

Returns the features for this Artifact

pub fn memory_styles(&self) -> &PrimaryMap<MemoryIndex, MemoryStyle>[src]

Returns the memory styles associated with this Artifact.

pub fn table_styles(&self) -> &PrimaryMap<TableIndex, TableStyle>[src]

Returns the table plans associated with this Artifact.

pub fn data_initializers(&self) -> &[OwnedDataInitializer][src]

Returns data initializers to pass to InstanceHandle::initialize

pub fn finished_functions(
    &self
) -> &BoxedSlice<LocalFunctionIndex, FunctionBodyPtr>[src]

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

pub fn finished_function_call_trampolines(
    &self
) -> &BoxedSlice<SignatureIndex, VMTrampoline>[src]

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

pub fn finished_dynamic_function_trampolines(
    &self
) -> &BoxedSlice<FunctionIndex, FunctionBodyPtr>[src]

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

pub fn signatures(&self) -> &BoxedSlice<SignatureIndex, VMSharedSignatureIndex>[src]

Returns the associated VM signatures for this Artifact.

pub fn serialize(&self) -> Result<Vec<u8>, SerializeError>[src]

Serializes an artifact into bytes

Provided methods

pub fn serialize_to_file(&self, path: &Path) -> Result<(), SerializeError>[src]

Serializes an artifact into a file path

pub fn preinstantiate(&self) -> Result<(), InstantiationError>[src]

Do preinstantiation logic that is executed before instantiating

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

Crate an Instance from this Artifact.

Safety

See InstanceHandle::new.

pub unsafe fn finish_instantiation(
    &self,
    handle: &InstanceHandle
) -> Result<(), InstantiationError>[src]

Finishes the instantiation of a just created InstanceHandle.

Safety

See InstanceHandle::finish_instantiation.
