Expand description

A trait that defines an abstract wasm module instance.

This can be implemented by an execution engine.

Required Methods§

source

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.

Provided Methods§

source

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.

source

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.
