Struct GcVM 

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_global_names(&mut self, names: Vec<(String, usize)>)

Record which global slot each source-level global name refers to, so reports can state the named root set (see GlobalRoot).

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 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
