Timestamp

Struct Timestamp 

Source
pub struct Timestamp(/* private fields */);
Expand description

The timestamp for values in the database.

This is an absolute time point, represented as a floating point time_t value with arbitrary resolutions, typically in the microsecond range.

Implementations§

Source§

impl Timestamp

Source

pub fn now() -> Self

Creates a timestamp for the current time.

Source

pub fn with_resolution(st: SystemTime, res: Duration) -> Self

Creates a timestamp with a specific resolution

Source

pub fn with_resolution_f64(st: SystemTime, res: f64) -> Self

Creates a timestamp with a resolution specified as floating point seconds.

So, for microsecond resolution use 1.0e-6; for millisecond resolution, 1.0e-3, etc.

Source

pub fn as_f64(&self) -> f64

Gets the time stamp as a floating-point time_t value.

Source

pub fn into_system_time(self) -> SystemTime

Converts the time stamp to a system time value.
