Struct linera_base::data_types::Timestamp

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

Implementations

impl Timestamp

pub fn now() -> Timestamp

Returns the current time according to the system clock.

pub fn micros(&self) -> u64

Returns the number of microseconds since the Unix epoch.

pub fn saturating_diff_micros(&self, other: Timestamp) -> u64

Returns the number of microseconds from other until self, or 0 if other is not earlier than self.

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

Returns the timestamp that is duration later than self.

pub fn saturating_add_micros(&self, micros: u64) -> Timestamp

Returns a timestamp micros microseconds later than self, or the highest possible value if it would overflow.

pub fn saturating_sub_micros(&self, micros: u64) -> Timestamp

Returns a timestamp micros microseconds earlier than self, or the lowest possible value if it would underflow.
