Implementations

impl DeviceReading

pub fn encode(&self, at_ns: u64) -> [u64; 14]

2026-09-26: The word form a crate::seqcell::SeqCell carries.

pub fn decode(w: &[u64; 14]) -> (Self, u64)

2026-09-26: Inverse of DeviceReading::encode: the reading and its time.

Trait Implementations

impl Clone for DeviceReading

fn clone(&self) -> DeviceReading

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeviceReading

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

Formats the value using the given formatter.

impl Default for DeviceReading

fn default() -> DeviceReading

Returns the “default value” for a type.

impl PartialEq for DeviceReading

fn eq(&self, other: &DeviceReading) -> 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.

impl Serialize for DeviceReading

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for DeviceReading

impl Eq for DeviceReading

impl StructuralPartialEq for DeviceReading
