Struct UpValOpen 

pub struct UpValOpen { /* private fields */ }

Non-owning view of an open-upvalue list record.

Unsafe operations require a live open upvalue in the owning VM and valid neighboring list links; mutation must preserve both open-upvalue lists.

Implementations

impl UpValOpen

pub const unsafe fn from_raw(raw: NonNull<RawUpValOpen>) -> Self

pub unsafe fn prev(&self) -> UpVal

pub unsafe fn set_prev(&self, prev: UpVal)

pub unsafe fn next(&self) -> UpVal

pub unsafe fn set_next(&self, next: UpVal)

pub unsafe fn thread_next(&self) -> Option<UpVal>

pub unsafe fn set_thread_next(&self, thread_next: Option<UpVal>)
