Struct wasmtime_jit::CompiledModule

pub struct CompiledModule { /* fields omitted */ }

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 unsafe fn instantiate(
    &self,
    resolver: &mut dyn Resolver,
    signature_registry: &mut SignatureRegistry,
    mem_creator: Option<&dyn RuntimeMemoryCreator>,
    interrupts: Arc<VMInterrupts>,
    host_state: Box<dyn Any>,
    externref_activations_table: *mut VMExternRefActivationsTable,
    stack_map_registry: *mut StackMapRegistry
) -> 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) -> Option<&mut Module>

Return a reference to a mutable module (if possible).

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 map for all traps in this module.

pub fn stack_maps(&self) -> &StackMaps

Returns the map for each of this module’s stack maps.

pub fn address_transform(&self) -> &ModuleAddressMap

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

pub fn jit_code_ranges<'a>(
    &'a self
) -> impl Iterator<Item = (usize, usize)> + 'a

Returns all ranges convered by JIT code.

pub fn code(&self) -> &Arc<ModuleCode>

Returns module’s JIT code.
