Struct Vm 

pub struct Vm<'vm> { /* private fields */ }

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.

Error Handling

Behavior varies based on the numeric backend:

• f64 mode: Relaxed error handling. Only catches errors that would cause panics. Allows Inf and NaN results from operations like 1/0 or sqrt(-1).

• Decimal mode: Strict error handling. All arithmetic operations are checked for overflow/underflow. Returns errors for domain violations.

Implementations

impl<'vm> Vm<'vm>

pub fn run( bytecode: &'vm [Instr], symtable: &'vm mut SymTable, ) -> Result<Number, VmError>

Executes bytecode 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
• Invalid jumps
