Struct Timestamp 

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

A Unix timestamp with nanosecond precision.

Implementations

impl Timestamp

pub const MIN: Timestamp

The minimum timestamp, 1970-01-01T00:00:00Z.

pub const MAX: Timestamp

The maximum timestamp, 9999-12-31T23:59:59.999999999Z.

pub fn from_unix(unix_time: Duration) -> Option<Timestamp>

Try create a timestamp from time since the Unix epoch.

If the unix_time is within Timestamp::MIN..=Timestamp::MAX then this method will return Some. Otherwise it will return None.

pub fn to_unix(&self) -> Duration

Get the value of the timestamp as time since the Unix epoch.

pub fn try_from_str(ts: &str) -> Result<Timestamp, ParseTimestampError>

Try parse a timestamp from an RFC3339 formatted representation.

pub fn parse(ts: impl Display) -> Result<Timestamp, ParseTimestampError>

Try parse a timestamp from an RFC3339 formatted value.

pub fn duration_since(self, earlier: Timestamp) -> Option<Duration>

Calculate the timespan between two timestamps.

This method will return None if earlier is actually after self.

pub fn from_system_time(ts: SystemTime) -> Option<Timestamp>

Convert a system timestamp into a timestamp.

If the ts is within Timestamp::MIN..=Timestamp::MAX then this method will return Some. Otherwise it will return None.

pub fn to_system_time(&self) -> SystemTime

Convert the timestamp into a system timestamp.

This method can be used for interoperability with code expecting a standard library timestamp.

pub fn from_parts(parts: Parts) -> Option<Timestamp>

Try get a timestamp from its individual date and time parts.

If the resulting timestamp is within Timestamp::MIN..=Timestamp::MAX then this method will return Some. Otherwise it will return None.

If any field of parts would overflow its maximum value, such as days: 32, then it will wrap into the next unit.

pub fn to_parts(&self) -> Parts

Get the individual date and time parts of the timestamp.

The returned parts are in exactly the form needed to display them. Months and days are both one-based.

pub fn checked_add(&self, rhs: Duration) -> Option<Timestamp>

Add a duration to this timestamp.

If the result would be greater than Timestamp::MAX then None is returned.

pub fn checked_sub(&self, rhs: Duration) -> Option<Timestamp>

Subtract a duration to this timestamp.

If the result would be less than Timestamp::MIN then None is returned.

pub fn checked_duration_since(&self, earlier: Timestamp) -> Option<Duration>

Get the duration between this timestamp and an earlier one.
