Struct webpki::Time

source ·
pub struct Time(_);
Expand description

The time type.

Internally this is merely a UNIX timestamp: a count of non-leap seconds since the start of 1970. This type exists to assist unit-of-measure correctness.

Implementations§

source§

impl Time

source

pub fn from_seconds_since_unix_epoch(secs: u64) -> Self

Create a webpki::Time from a unix timestamp.

It is usually better to use the less error-prone webpki::Time::try_from(time: std::time::SystemTime) instead when std::time::SystemTime is available (when #![no_std] isn’t being used).

impl PartialEq<Time> for Time

source§

fn eq(&self, other: &Time) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<SystemTime> for Time

source§

fn try_from(value: SystemTime) -> Result<Self, Self::Error>

Create a webpki::Time from a std::time::SystemTime.

Example:

Construct a webpki::Time from the current system time:

#![cfg(feature = "std")]
use std::{convert::TryFrom, time::{SystemTime, SystemTimeError}};

let time = webpki::Time::try_from(SystemTime::now())?;
§

type Error = SystemTimeError

The type returned in the event of a conversion error.
