Struct GlobalState 

pub struct GlobalState { /* private fields */ }

Non-owning identity of a VM’s global state record.

Safety model for unsafe methods

The owning VM must remain live. Returned threads, objects, pointers, and record views are non-owning and must not outlive their storage. Mutation must be serialized with VM execution and preserve the owning subsystem’s invariants.

impl GlobalState

pub fn all_gco_pages(&self) -> Option<LuaPage>

pub fn sweep_gco_page(&self) -> Option<LuaPage>

impl GlobalState

pub unsafe fn type_name(&self, tag: usize) -> TString

pub unsafe fn tm_name(&self, event: usize) -> TString

pub fn metatable(&self, tag: usize) -> Option<Table>

impl GlobalState

pub fn callbacks(&self) -> *mut LuaCallbacks

Returns the VM-owned public callback record address.

The pointer is for quiescent installation and focused VM reads. It does not establish a Rust borrow and must not be used to mutate the record while the VM is executing.

pub fn execution_callbacks(&self) -> *mut LuaExecutionCallbacks

Returns the VM-owned execution callback record address.

The pointer is for quiescent installation and focused VM reads. It does not establish a Rust borrow and must not be used to mutate the record while the VM is executing.
