Struct SendReceipt 

pub struct SendReceipt(pub u32);

Opaque tracking token returned for ACK-requested transmissions.

When Mac::queue_unicast or Mac::queue_blind_unicast is called with options.ack_requested = true, the coordinator allocates a SendReceipt from the identity slot’s internal sequence counter and returns it wrapped in Some(...). The application stores this token and watches for it to appear in a future MAC event callback — either confirming delivery (MAC ACK received and verified) or reporting failure (all retransmit attempts exhausted without a valid ACK).

Receipts are unique within the lifetime of an IdentitySlot (wrapping after ~4 billion sends). They are not meaningful across reboots or after the identity slot is removed.

Trait Implementations

impl Clone for SendReceipt

fn clone(&self) -> SendReceipt

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SendReceipt

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

Formats the value using the given formatter.

impl Hash for SendReceipt

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SendReceipt

fn eq(&self, other: &SendReceipt) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
