Struct Vm 

pub struct Vm<'a> {
    pub step_limit: u64,
    pub steps: u64,
    /* private fields */
}

Fields

step_limit: u64

Soft cap to avoid runaway computations in tests.

steps: u64

Implementations

impl<'a> Vm<'a>

pub fn new(program: &'a Program) -> Self

pub fn with_handler( program: &'a Program, handler: Box<dyn EffectHandler + 'a>, ) -> Self

pub fn set_tracer(&mut self, tracer: Box<dyn Tracer + 'a>)

pub fn set_step_limit(&mut self, limit: u64)

Cap the number of opcode dispatches before the VM aborts with step limit exceeded. Useful as a runtime DoS guard against untrusted code (e.g. the agent-tool sandbox, where an LLM could emit list.fold(list.range(0, 1_000_000_000), …) to hang the host). Default is 10_000_000.

pub fn call(&mut self, name: &str, args: Vec<Value>) -> Result<Value, VmError>

pub fn invoke(&mut self, fn_id: u32, args: Vec<Value>) -> Result<Value, VmError>
