Struct UpVal 

pub struct UpVal { /* private fields */ }

Non-owning identity of a VM upvalue record.

Safety model for unsafe methods

The upvalue, its value slot, and any stack used for rebasing must remain live in the same VM. Callers must preserve open-list ordering and closed storage state while moving or closing it.

Implementations

impl UpVal

pub unsafe fn open_data(&self) -> UpValOpen

pub unsafe fn value_ptr(&self) -> *mut RawTValue

pub unsafe fn value(&self) -> TValue

pub unsafe fn closed_value(&self) -> TValue

pub unsafe fn set_value(&self, value: TValue)

pub unsafe fn rebase_value( &self, old_stack: TValueCursor, new_stack: TValueCursor, )

impl Clone for UpVal

fn clone(&self) -> UpVal

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for UpVal

impl Eq for UpVal

impl From<UpVal> for GcObject

fn from(value: UpVal) -> Self

Inequality operator !=.

impl RawHandle for UpVal

type Raw = RawUpVal

Raw VM record addressed by this handle.

fn as_ptr(&self) -> *mut Self::Raw
