Struct DateTime

Source
pub struct DateTime { /* private fields */ }
Expand description

DateTime in time.

DateTime in time represented as seconds and sub-second nanos since the Unix epoch (January 1, 1970 at midnight UTC/GMT).

This type can be converted to/from the standard library’s SystemTime:

use std::convert::TryFrom;

let the_millennium_as_system_time = SystemTime::try_from(DateTime::from_secs(946_713_600))?;
let now_as_date_time = DateTime::from(SystemTime::now());

The aws-smithy-types-convert crate can be used for conversions to/from other libraries, such as time or chrono.

Implementations§

Source§

impl DateTime

Source

pub fn from_secs(epoch_seconds: i64) -> DateTime

Creates a DateTime from a number of seconds since the Unix epoch.

Source

pub fn from_millis(epoch_millis: i64) -> DateTime

Creates a DateTime from a number of milliseconds since the Unix epoch.

Source

pub fn from_nanos(epoch_nanos: i128) -> Result<DateTime, ConversionError>

Creates a DateTime from a number of nanoseconds since the Unix epoch.

Source

pub fn as_nanos(&self) -> i128

Returns the number of nanoseconds since the Unix epoch that this DateTime represents.

Source

pub fn from_fractional_secs(epoch_seconds: i64, fraction: f64) -> DateTime

Creates a DateTime from a number of seconds and a fractional second since the Unix epoch.

§Example
assert_eq!(
    DateTime::from_secs_and_nanos(1, 500_000_000u32),
    DateTime::from_fractional_secs(1, 0.5),
);
Source

pub fn from_secs_and_nanos(seconds: i64, subsecond_nanos: u32) -> DateTime

Creates a DateTime from a number of seconds and sub-second nanos since the Unix epoch.

§Example
assert_eq!(
    DateTime::from_fractional_secs(1, 0.5),
    DateTime::from_secs_and_nanos(1, 500_000_000u32),
);
Source

pub fn as_secs_f64(&self) -> f64

Returns the DateTime value as an f64 representing the seconds since the Unix epoch.

Note: This conversion will lose precision due to the nature of floating point numbers.

Source

pub fn from_secs_f64(epoch_seconds: f64) -> DateTime

Creates a DateTime from an f64 representing the number of seconds since the Unix epoch.

§Example
assert_eq!(
    DateTime::from_fractional_secs(1, 0.5),
    DateTime::from_secs_f64(1.5),
);
Source

pub fn from_str(s: &str, format: Format) -> Result<DateTime, DateTimeParseError>

Parses a DateTime from a string using the given format.

Source

pub fn has_subsec_nanos(&self) -> bool

Returns true if sub-second nanos is greater than zero.

Source

pub fn secs(&self) -> i64

Returns the epoch seconds component of the DateTime.

Note: this does not include the sub-second nanos.

Source

pub fn set_seconds(&mut self, seconds: i64) -> &mut DateTime

Set the seconds component of this DateTime.

Source

pub fn subsec_nanos(&self) -> u32

Returns the sub-second nanos component of the DateTime.

Note: this does not include the number of seconds since the epoch.

Source

pub fn set_subsec_nanos(&mut self, subsec_nanos: u32) -> &mut DateTime

Set the “sub-second” nanoseconds of this DateTime.

Source

pub fn to_millis(self) -> Result<i64, ConversionError>

Converts the DateTime to the number of milliseconds since the Unix epoch.

This is fallible since DateTime holds more precision than an i64, and will return a ConversionError for DateTime values that can’t be converted.

Source

pub fn read( s: &str, format: Format, delim: char, ) -> Result<(DateTime, &str), DateTimeParseError>

Read 1 date of format from s, expecting either delim or EOF

Enable parsing multiple dates from the same string

Source

pub fn fmt(&self, format: Format) -> Result<String, DateTimeFormatError>

Formats the DateTime to a string using the given format.

Returns an error if the given DateTime cannot be represented by the desired format.
