Implementations§
source§impl Executor
impl Executor
sourcepub fn create(
config: Option<&Config>,
stat: Option<Statistics>
) -> WasmEdgeResult<Self>
pub fn create( config: Option<&Config>, stat: Option<Statistics> ) -> WasmEdgeResult<Self>

async and Linux and non-musl only.Asynchronously runs a host function instance with a timeout setting
§Arguments
-
async_state- Used to store asynchronous state at run time. -
func- The function instance to run. -
params- The arguments to pass to the function. -
timeout- The maximum execution time of the function to be run.
§Errors
If fail to run the host function, then an error is returned.

async and Linux only.Asynchronously runs a host function reference instance and returns the results.
§Arguments
-
async_state- Used to store asynchronous state at run time. -
func_ref- The function reference instance to run. -
params- The arguments to pass to the function.
§Errors
If fail to run the host function reference instance, then an error is returned.

sourcepub fn register_import_module<T: AsInstance + ?Sized>(
&mut self,
store: &mut Store,
import: &T
) -> WasmEdgeResult<()>
pub fn register_import_module<T: AsInstance + ?Sized>( &mut self, store: &mut Store, import: &T ) -> WasmEdgeResult<()>
Registers and instantiates a import module into a store.
§Arguments
-
store- The target store, into which the given import module is registered. -
import- The WasmEdge import module to be registered.
§Error
If fail to register the given import module, then an error is returned.
sourcepub fn register_named_module(
&mut self,
store: &mut Store,
module: &Module,
name: impl AsRef<str>
) -> WasmEdgeResult<Instance>
pub fn register_named_module( &mut self, store: &mut Store, module: &Module, name: impl AsRef<str> ) -> WasmEdgeResult<Instance>
Registers and instantiates a WasmEdge module into a store.
Instantiates the given WasmEdge module, including the functions, memories, tables, and globals it hosts; and then, registers the module instance into the store with the given name.
§Arguments
-
store- The target store, into which the given module is registered. -
module- A validated module to be registered. -
name- The exported name of the registered module.
§Error
If fail to register the given module, then an error is returned.
sourcepub fn register_active_module(
&mut self,
store: &mut Store,
module: &Module
) -> WasmEdgeResult<Instance>
pub fn register_active_module( &mut self, store: &mut Store, module: &Module ) -> WasmEdgeResult<Instance>
Registers and instantiates a WasmEdge module into a store as an anonymous module.
Notice that when a new module is instantiated into the store, the old instantiated module is removed; in addition, ensure that the imports the module depends on are already registered into the store.
§Arguments
-
store- The store, in which the module to be instantiated is stored. -
ast_mod- The target module to be instantiated.
§Error
If fail to instantiate the given module, then an error is returned.
