Struct alloc_data::prelude::time::Date

pub struct Date { /* private fields */ }

An actual, absolute date.

As opposed to SinceStart which represents a point in time as a duration since the start date of the run of the program being profiled.

In practice, this type is just a wrapper around a chrono date.

Implementations

impl Date

pub fn from_timestamp(secs: i64, nanos: u32) -> Date

Constructor from a unix timestamp.

Examples

use base::prelude::time::*;
let (secs, subsec_nanos) = (1566489242, 7000572);
let date = Date::from_timestamp(secs, subsec_nanos);
assert_eq! { date.timestamp(), (secs, subsec_nanos) }

pub fn now() -> Date

The current date.

pub fn from_micros(micros: u64) -> Date

Constructor from an ocaml duration.

Examples

use base::prelude::time::*;
let secs = 156648924_u64;
let subsec_micros = 270005_u32;
let micros = secs * 1_000_000 + (subsec_micros as u64);
let date = Date::from_micros(micros);
assert_eq! { date.timestamp(), (secs as i64, subsec_micros * 1_000) }

pub fn date(&self) -> &DateTime<Local>

Date accessor.

pub fn timestamp(&self) -> (i64, u32)

Timestamp version of a date.

Returns a pair ( timestamp’s seconds , timestamp’s subsec nanoseconds ).

Examples

use base::prelude::time::*;
let (secs, subsec_nanos) = (1_566_489_242, 7_000_572);
let date = Date::from_timestamp(secs, subsec_nanos);
assert_eq! { date.timestamp(), (secs, subsec_nanos) }

pub fn time_info(&self) -> (u32, u32, u32, u32)

The hours/minutes/seconds/millis of a date.

This is currently used only for debugging purposes.

Examples

use base::prelude::time::*;
let mut date = Date::from_timestamp(1566489242, 7000572);
let (_h, m, s, mi) = date.time_info();
// Can't check the hours as this depends on the local system time.
assert_eq! {  m, 54 }
assert_eq! {  s, 2 }
assert_eq! { mi, 7 }
