Struct TimestampMs 

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

Implementations

impl TimestampMs

pub const MIN: Self

pub const MAX: Self

pub fn now() -> Self

Creates a new TimestampMs from the current SystemTime.

Panics if the current time is not within bounds.

pub fn to_i64(self) -> i64

Get this unix timestamp as an i64 in milliseconds from unix epoch.

pub fn to_u64(self) -> u64

Get this unix timestamp as a u64 in milliseconds from unix epoch.

pub fn from_secs(secs: u64) -> Result<Self, Error>

Construct TimestampMs from seconds since Unix epoch.

pub fn from_secs_u32(secs: u32) -> Self

Infallibly construct TimestampMs from seconds since Unix epoch.

pub fn from_millis(millis: u64) -> Result<Self, Error>

Construct TimestampMs from milliseconds since Unix epoch.

pub fn from_duration(dur_since_epoch: Duration) -> Result<Self, Error>

Construct TimestampMs from Duration since Unix epoch.

pub fn from_system_time(system_time: SystemTime) -> Result<Self, Error>

Construct TimestampMs from a SystemTime.

pub fn to_millis(self) -> u64

Get this unix timestamp as a u64 in milliseconds from unix epoch.

pub fn to_secs(self) -> u64

Get this unix timestamp as a u64 in seconds from unix epoch.

pub fn to_duration(self) -> Duration

Get this unix timestamp as a Duration from the unix epoch.

pub fn to_system_time(self) -> SystemTime

Get this unix timestamp as a SystemTime.

pub fn checked_add(self, duration: Duration) -> Option<Self>

pub fn checked_sub(self, duration: Duration) -> Option<Self>

pub fn saturating_add(self, duration: Duration) -> Self

pub fn saturating_sub(self, duration: Duration) -> Self

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

Returns the Duration elapsed from earlier to self, or None if earlier is later than self.

pub fn saturating_duration_since(self, earlier: Self) -> Duration

Returns the Duration elapsed from earlier to self, saturating to Duration::ZERO if earlier is later than self.

pub fn checked_elapsed(self) -> Option<Duration>

Returns the Duration elapsed since this timestamp, or None if it is in the future.

pub fn saturating_elapsed(self) -> Duration

Returns the Duration elapsed since this timestamp, saturating to Duration::ZERO if it is in the future.

pub fn to_relative_string(self, now: Self) -> String

Formats this timestamp into a human-readable string relative to now, e.g. “just now”, “5 minutes ago”, “in 3 hours”, “in 2 years and 5 weeks”.

Picks the largest whole unit that fits; weeks and years also carry the remainder in the next unit down. Sub-second differences in either direction read as “just now”.
