Trait sc_executor_common::wasm_runtime::WasmRuntime

pub trait WasmRuntime {
    fn host_functions(&self) -> &[&'static dyn Function];
    fn call(&mut self, method: &str, data: &[u8]) -> Result<Vec<u8>, Error>;
    fn get_global_val(&self, name: &str) -> Result<Option<Value>, Error>;
}

A trait that defines an abstract wasm runtime.

This can be implemented by an execution engine.

Required methods

fn host_functions(&self) -> &[&'static dyn Function]

Return the host functions that are registered for this Wasm runtime.

fn call(&mut self, method: &str, data: &[u8]) -> Result<Vec<u8>, Error>

Call a method in the Substrate runtime by name. Returns the encoded result on success.

fn get_global_val(&self, name: &str) -> Result<Option<Value>, Error>

Get the value from a global with the given name.
