    ) -> 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_with_allocation_stats( &mut self, method: &str, data: &[u8], ) -> (Result<Vec<u8>, Error>, Option<AllocationStats>)

Call a method on this WASM instance.

Before execution, instance is reset.

Returns the encoded result on success.

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

Get the value from a global with the given name.

This method is only suitable for getting immutable globals.

Provided Methods

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

Call a method on this WASM instance.

Before execution, instance is reset.

Returns the encoded result on success.

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

Call an exported method on this WASM instance.

Before execution, instance is reset.

Returns the encoded result on success.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
