Struct Timestamp 

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

A point in time, stored as microseconds since Unix epoch.

Microsecond precision, covering roughly 290,000 years in each direction from 1970. Create with from_secs(), from_millis(), or now().

Implementations

impl Timestamp

pub const EPOCH: Self

The Unix epoch (1970-01-01 00:00:00 UTC).

pub const MIN: Self

The minimum representable timestamp.

pub const MAX: Self

The maximum representable timestamp.

pub const fn from_micros(micros: i64) -> Self

Creates a timestamp from microseconds since the Unix epoch.

pub const fn from_millis(millis: i64) -> Self

Creates a timestamp from milliseconds since the Unix epoch.

pub const fn from_secs(secs: i64) -> Self

Creates a timestamp from seconds since the Unix epoch.

pub fn now() -> Self

Returns the current time as a timestamp.

pub const fn as_micros(&self) -> i64

Returns the timestamp as microseconds since the Unix epoch.

pub const fn as_millis(&self) -> i64

Returns the timestamp as milliseconds since the Unix epoch.

pub const fn as_secs(&self) -> i64

Returns the timestamp as seconds since the Unix epoch.

pub fn as_system_time(&self) -> Option<SystemTime>

Returns the timestamp as a SystemTime, if it’s within the representable range.

pub const fn add_micros(self, micros: i64) -> Self

Adds a duration to this timestamp.

pub const fn sub_micros(self, micros: i64) -> Self

Subtracts a duration from this timestamp.

pub const fn duration_since(self, other: Self) -> i64

Returns the duration between this timestamp and another.

Returns a positive value if other is before self, negative otherwise.

Trait Implementations

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 Default for Timestamp

fn default() -> Timestamp

Returns the “default value” for a type.

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 Display for Timestamp

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

Formats the value using the given formatter.

impl From<Timestamp> for Value

fn from(t: Timestamp) -> Self

Converts to this type from the input type.

impl From<Timestamp> for i64

fn from(ts: Timestamp) -> Self

Converts to this type from the input type.

impl From<i64> for Timestamp

fn from(micros: i64) -> Self

Converts to this type from the input type.

impl Hash for Timestamp

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 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.

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.

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.

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<SystemTime> for Timestamp

type Error = ()

The type returned in the event of a conversion error.

fn try_from(time: SystemTime) -> Result<Self, Self::Error>

Performs the conversion.
