Trait InstructionHandler

pub trait InstructionHandler
where
    Self: Sized,
{
    type Context;
    type Err;

    // Required methods
    fn create_vm(initial_context: Self::Context) -> VM<Self>;
    fn process_instruction(
        vm_state: &mut VMState,
        context: &mut Self::Context,
        instruction: Instruction,
    ) -> Result<(), Self::Err>;
}

An instruction handler interface.

Required Associated Types

type Context

Handler context.

type Err

Err return type after processing instructions. TODO: Convert Err into std::ops::Try once it is stabilized

Required Methods

fn create_vm(initial_context: Self::Context) -> VM<Self>

fn process_instruction( vm_state: &mut VMState, context: &mut Self::Context, instruction: Instruction, ) -> Result<(), Self::Err>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
