Struct Handle 

pub struct Handle(/* private fields */);

A batching-callback slot handle: a binding-private slot index (into the hook’s pending-value table) packed with an optional splice-flag high bit. A repr(transparent) u32 newtype so the packed word — like Action — is reachable only through its accessors, never as a bare integer.

Implementations

impl Handle

pub const MAX_SLOT: u32

Largest slot index that fits below the splice-flag bit; the batching binding must keep its slot table within this ceiling.

pub fn new(index: u32) -> Handle

A handle over slot index, no splice flag (index <= MAX_SLOT, debug-asserted — the flag owns the high bit).

pub fn slot(self) -> u32

The slot index, splice flag masked off.

pub fn has_splice_flag(self) -> bool

Whether drain_hook_return marked this as a _-splice child (inline the slot value’s .children into the parent, not the value itself).

pub fn with_splice_flag(self) -> Handle

The same handle with the splice flag set.
