LuaNodeCursor

Struct LuaNodeCursor 

Source
pub struct LuaNodeCursor(/* private fields */);
Expand description

Nullable traversal position in a table’s hash-node array.

Unsafe navigation requires cursors from the same live node allocation and an in-bounds non-null position where a node is accessed. Resizing the table invalidates every cursor.

Implementations§

Source§

impl LuaNodeCursor

Source

pub const fn as_ptr(&self) -> *mut RawLuaNode

Returns the current traversal address, which may be null.

Table resize and rehash invalidate cursors into the old node array.

Source

pub const fn from_ptr(raw: *mut RawLuaNode) -> Self

Source

pub const fn is_null(&self) -> bool

Source

pub unsafe fn node_unchecked(&self) -> LuaNode

Source

pub fn node(&self) -> Option<LuaNode>

Source

pub unsafe fn add(self, count: usize) -> Self

Source

pub unsafe fn sub(self, count: usize) -> Self

Source

pub unsafe fn offset(self, count: isize) -> Self

Source

pub unsafe fn offset_from(self, other: Self) -> isize
