Struct Vm 

pub struct Vm;

Stack-based virtual machine for executing bytecode programs.

The VM evaluates programs by executing bytecode instructions on a stack, performing arithmetic operations and function calls.

Implementations

impl Vm

pub fn run_bytecode( &self, bytecode: &[Instr], table: &SymTable, ) -> Result<Decimal, VmError>

Executes bytecode directly and returns the result.

Errors

Returns VmError if execution fails due to:

• Stack underflow
• Division by zero
• Invalid operations (e.g., factorial of non-integer)
• Function errors
• Invalid symbol indices

Trait Implementations

impl Debug for Vm

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Vm

fn default() -> Vm

Returns the “default value” for a type.
