Struct ReplSession 

pub struct ReplSession<'i, H> { /* private fields */ }

A persistent REPL session against an Interpreter<H>.

Multiple calls to eval_str share the same global env — bindings introduced by one call are visible to subsequent calls. Errors in one call do not poison the session.

Implementations

impl<'i, H: 'static> ReplSession<'i, H>

pub fn new(interp: &'i mut Interpreter<H>) -> Self

pub fn eval_str(&mut self, input: &str, host: &mut H) -> Result<Value>

Evaluate one or more forms from input in the session’s env, returning the value of the last form. Phase 2.5 fills this in.

pub fn is_complete(input: &str) -> bool

Paren-balance check — returns true when input is a complete set of top-level forms (ready to submit) or false when the user’s client should keep collecting more input.

Phase 2.2: minimal heuristic (open-paren count vs close-paren count, ignoring string literals). Phase 2.5 refines.
