Trait sc_executor_common::wasm_runtime::WasmInstance [−][src]
pub trait WasmInstance: Send { fn call(
&self,
method: InvokeMethod<'_>,
data: &[u8]
) -> Result<Vec<u8>, Error>; fn get_global_const(&self, name: &str) -> Result<Option<Value>, Error>; fn call_export(&self, method: &str, data: &[u8]) -> Result<Vec<u8>, Error> { ... } }
A trait that defines an abstract wasm module instance.
This can be implemented by an execution engine.
Required methods
fn call(&self, method: InvokeMethod<'_>, data: &[u8]) -> Result<Vec<u8>, Error>[src]
Call a method on this WASM instance.
Before execution, instance is reset.
Returns the encoded result on success.
fn get_global_const(&self, name: &str) -> Result<Option<Value>, Error>[src]
Get the value from a global with the given name.
This method is only suitable for getting immutable globals.
Provided methods
fn call_export(&self, method: &str, data: &[u8]) -> Result<Vec<u8>, Error>[src]
Call an exported method on this WASM instance.
Before execution, instance is reset.
Returns the encoded result on success.
