Struct OptionData 

pub struct OptionData {
    pub is_some: bool,
    pub payload: KindedSlot,
}

Option carrier. is_some discriminates Some vs None; payload carries the inner value for Some. For None the payload is a KindedSlot::none() placeholder (Bool-kind, zero bits) so KindedSlot::Drop is a no-op.

Fields

is_some: bool

payload: KindedSlot

Implementations

impl OptionData

pub fn some(payload: KindedSlot) -> Self

Construct a Some-tagged option.

pub fn none() -> Self

Construct a None-tagged option (payload is a no-op KindedSlot).

Trait Implementations

impl Clone for OptionData

fn clone(&self) -> Self

Per-field clone — KindedSlot::Clone bumps the payload’s strong-count share. For None the payload is a zero-bits Bool slot; clone is a no-op refcount-wise.

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

Performs copy-assignment from source.

impl Debug for OptionData

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
