pub struct GcVM { /* private fields */ }

Implementations

impl GcVM

pub fn new(bytecode: Bytecode) -> Self

pub fn load_bytecode(&mut self, bytecode: Bytecode)

Replace the current main program while preserving the heap and globals.

Used by the REPL so later lines can read bindings created earlier. Old constant-pool owning refs are released; objects still reachable from globals stay alive.

pub fn heap(&self) -> &GcHeap

pub fn heap_mut(&mut self) -> &mut GcHeap

pub fn set_capture_output(&mut self, capture: bool)

Capture puts/print output in-memory instead of writing to stdout.

pub fn take_output(&mut self) -> String

Drain captured output while leaving capture enabled.

pub fn set_global_bindings(&mut self, bindings: Vec<BindingDebugInfo>)

Record the compiler’s global definition ledger (slot order, rebindings included), used by GC reports for the named root set (see GlobalRoot) and by debugger snapshots for slot names.

pub fn globals_initialized(&self) -> &[bool]

One flag per global slot: has OpSetGlobal written it? Debugger snapshots use this to tell a user-assigned null from a never-run let.

pub fn take_debugger_hits(&mut self) -> (Vec<DebuggerHit>, usize)

Drain recorded debugger; snapshots plus the count of hits dropped after MAX_DEBUGGER_HITS. Recording resumes from zero afterwards.

pub fn collect_garbage(&mut self) -> GcCollectionReport

pub fn run(&mut self)

pub fn run_with_budget( &mut self, instruction_budget: usize, ) -> Result<(), GcRuntimeError>

pub fn run_with_budget_classified( &mut self, instruction_budget: usize, ) -> Result<(), GcClassifiedRuntimeError>

Execute with a budget and retain the category assigned at the raise site.

pub fn last_popped_stack_elm(&self) -> Option<GcRef>

pub fn export_last_result(&self) -> Option<Object>

pub fn try_export_last_result(&self) -> Result<Object, String>

pub fn last_result_string(&self) -> String
