Struct Timestamp 

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

Time in nanoseconds from std::time::UNIX_EPOCH.

Used as an ID+Timestamp for an Action`. Each action will have an unique id. If two actions happen at the same time, id must be increased by 1 for second action, to ensure uniqueness of id.

u64 is enough to contain time in nanoseconds at most 584 years after UNIX_EPOCH (1970-01-01 00:00:00 UTC).

//           nano     micro  milli  sec    min  hour day  year
assert_eq!(u64::MAX / 1000 / 1000 / 1000 / 60 / 60 / 24 / 365, 584);

Implementations

impl Timestamp

Trait Implementations

impl Add<Duration> for Timestamp

type Output = Timestamp

The resulting type after applying the + operator.

fn add(self, other: Duration) -> Timestamp

Performs the + operation.

impl Add<u64> for Timestamp

type Output = Timestamp

The resulting type after applying the + operator.

fn add(self, other: u64) -> Timestamp

Performs the + operation.

impl Add for Timestamp

type Output = Timestamp

The resulting type after applying the + operator.

fn add(self, other: Timestamp) -> Timestamp

Performs the + operation.

impl Clone for Timestamp

fn clone(&self) -> Timestamp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Timestamp

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Timestamp

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<ActionId> for Timestamp

fn from(id: ActionId) -> Self

Converts to this type from the input type.

impl From<Timestamp> for SystemTime

fn from(value: Timestamp) -> Self

Converts to this type from the input type.

impl From<Timestamp> for u64

fn from(t: Timestamp) -> Self

Converts to this type from the input type.

impl Ord for Timestamp

fn cmp(&self, other: &Timestamp) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Timestamp

fn eq(&self, other: &Timestamp) -> 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 PartialOrd for Timestamp

fn partial_cmp(&self, other: &Timestamp) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Timestamp

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 Timestamp

impl Eq for Timestamp

impl StructuralPartialEq for Timestamp
