Struct Evaluator 

pub struct Evaluator<'a> { /* private fields */ }

Implementations

impl<'a> Evaluator<'a>

pub fn new(env: &'a mut Environment, program: &'a Program) -> Self

pub fn exec(&mut self) -> RexxResult<ExecSignal>

pub fn set_main_args(&mut self, args: Vec<RexxValue>)

Public setter so main.rs can push CLI arguments for the main program.

pub fn set_command_handler( &mut self, handler: Box<dyn FnMut(&str, &str) -> Option<i32>>, )

Set a custom command handler for ADDRESS environments.

The handler receives (address_environment, command_string) and returns:

• Some(rc) if it handled the command (rc is the return code)
• None if the command should fall through to default shell execution

This allows embedding applications (like XEDIT) to intercept commands sent to custom ADDRESS environments.

pub fn queue_len(&self) -> usize

Return the current queue length (for QUEUED() BIF).
