Struct concordium_std::Timestamp

#[repr(transparent)]
pub struct Timestamp { /* private fields */ }

Timestamp represented as milliseconds since unix epoch.

Timestamps from before January 1st 1970 at 00:00 are not supported.

Implementations

impl Timestamp

pub fn from_timestamp_millis(milliseconds: u64) -> Timestamp

Construct timestamp from milliseconds since unix epoch.

pub fn timestamp_millis(&self) -> u64

Milliseconds since the UNIX epoch.

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

Add duration to the timestamp. Returns None if the resulting timestamp is not representable, i.e., too far in the future.

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

Subtract duration from the timestamp. Returns None instead of overflowing if the resulting timestamp would be before the Unix epoch.

pub fn duration_between(self, other: Timestamp) -> Duration

Compute the duration between the self and another timestamp. The duration is always positive, and is the difference between the the more recent timestamp and the one further in the past.

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

Compute duration since a given timestamp. Returns None if given time is in the future compared to self.

Trait Implementations
