Struct aws_sdk_codepipeline::types::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 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 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.
