Struct CompiledModule

pub struct CompiledModule { /* private fields */ }

A compiled wasm module, ready to be instantiated.

Implementations

impl CompiledModule

pub fn new<'data>( compiler: &Compiler, data: &'data [u8], profiler: &dyn ProfilingAgent, ) -> Result<Self, SetupError>

Compile a data buffer into a CompiledModule, which may then be instantiated.

pub fn from_parts( module: Module, finished_functions: BoxedSlice<DefinedFuncIndex, *mut [VMFunctionBody]>, trampolines: HashMap<VMSharedSignatureIndex, VMTrampoline>, data_initializers: Box<[OwnedDataInitializer]>, signatures: BoxedSlice<SignatureIndex, VMSharedSignatureIndex>, dbg_jit_registration: Option<GdbJitImageRegistration>, traps: Traps, address_transform: ModuleAddressMap, interrupts: Arc<VMInterrupts>, ) -> Self

Construct a CompiledModule from component parts.

pub unsafe fn instantiate( &self, resolver: &mut dyn Resolver, sig_registry: &SignatureRegistry, mem_creator: Option<&dyn RuntimeMemoryCreator>, host_state: Box<dyn Any>, ) -> Result<InstanceHandle, InstantiationError>

Crate an Instance from this CompiledModule.

Note that if only one instance of this module is needed, it may be more efficient to call the top-level instantiate, since that avoids copying the data initializers.

Unsafety

See InstanceHandle::new

pub fn data_initializers(&self) -> Vec<DataInitializer<'_>>

Returns data initializers to pass to InstanceHandle::initialize

pub fn module(&self) -> &Arc<Module>

Return a reference-counting pointer to a module.

pub fn module_mut(&mut self) -> &mut Arc<Module>

Return a reference-counting pointer to a module.

pub fn module_ref(&self) -> &Module

Return a reference to a module.

pub fn finished_functions( &self, ) -> &BoxedSlice<DefinedFuncIndex, *mut [VMFunctionBody]>

Returns the map of all finished JIT functions compiled for this module

pub fn traps(&self) -> &Traps

Returns the a map for all traps in this module.

pub fn address_transform(&self) -> &ModuleAddressMap

Returns a map of compiled addresses back to original bytecode offsets.
