Required Methods

fn instantiate(&mut self, program: &[u8]) -> Result<Result<InstanceId, u8>>

fn run( &mut self, instance_id: InstanceId, gas_left: i64, action: ExecAction<'_>, ) -> Result<Result<ExecOutcome, u8>>

Execute or resume a virtualization instance.

When action is ExecAction::Execute, starts executing the named function. When action is ExecAction::Resume, resumes after a syscall with the given return value.

Returns the execution outcome: either finished or a syscall was encountered.

fn destroy(&mut self, instance_id: InstanceId) -> Result<Result<(), u8>>

fn read_memory( &mut self, instance_id: InstanceId, offset: u32, dest: &mut [u8], ) -> Result<Result<(), u8>>

fn write_memory( &mut self, instance_id: InstanceId, offset: u32, src: &[u8], ) -> Result<Result<(), u8>>
