Struct utc2k::Utc2k

pub struct Utc2k { /* private fields */ }

UTC2K.

This is a lightweight date/time object for UTC date ranges within the current century (e.g. 2000-01-01 00:00:00 to 2099-12-31 23:59:59).

Values outside this range are saturated to fit, unless using Utc2k::checked_from_unixtime.

To instantiate from a UTC unix timestamp, use From<u32>. To try to parse from a YYYY-MM-DD HH:MM:SS string, use TryFrom<&str>.

To manually construct from individual parts, you can just call Utc2k::new.

A Utc2k object can be turned back into its constituent parts via Utc2k::parts, or the individual methods like Utc2k::year, Utc2k::month, etc.

It can be converted into a unix timestamp with Utc2k::unixtime.

Examples

use utc2k::Utc2k;

let date = Utc2k::default(); // 2000-01-01 00:00:00
let date = Utc2k::now(); // The current time.
let date = Utc2k::from(4_102_444_799_u32); // 2099-12-31 23:59:59

// String parsing is fallible, but flexible. So long as the numbers we
// need are in the right place, it will be fine.
assert!(Utc2k::try_from("2099-12-31 23:59:59").is_ok()); // Fine.
assert!(Utc2k::try_from("2099-12-31T23:59:59.0000").is_ok()); // Also fine.
assert!(Utc2k::try_from("2099-12-31").is_ok()); // Also fine, but midnight.
assert!(Utc2k::try_from("January 1, 2010").is_err()); // Nope!

Implementations

impl Utc2k

Min/Max.

pub const MIN_UNIXTIME: u32

Minimum Timestamp.

pub const MAX_UNIXTIME: u32

Maximum Timestamp.

pub const fn min() -> Self

Minimum Value.

This is equivalent to 2000-01-01 00:00:00.

Examples

use utc2k::Utc2k;

let date = Utc2k::min();
assert_eq!(date.to_string(), "2000-01-01 00:00:00");

pub const fn max() -> Self

Maximum Value.

This is equivalent to 2099-12-31 23:59:59.

Examples

use utc2k::Utc2k;

let date = Utc2k::max();
assert_eq!(date.to_string(), "2099-12-31 23:59:59");

impl Utc2k

Instantiation.

pub fn new(y: u16, m: u8, d: u8, hh: u8, mm: u8, ss: u8) -> Self

New (From Parts).

This will create a new instance from individual year, month, etc., parts.

Overflowing units will be carried over where appropriate, so for example, 13 months becomes 1 year and 1 month.

Dates prior to 2000 or after 2099 will be saturated to fit.

Examples

use utc2k::Utc2k;

let date = Utc2k::new(2010, 5, 5, 16, 30, 1);
assert_eq!(date.to_string(), "2010-05-05 16:30:01");

pub fn now() -> Self

Now.

Create a new instance representing the current UTC time.

pub fn tomorrow() -> Self

Tomorrow.

Create a new instance representing one day from now (present time).

Examples

use utc2k::Utc2k;

assert_eq!(Utc2k::tomorrow(), Utc2k::now() + 86_400_u32);

pub fn yesterday() -> Self

Yesterday.

Create a new instance representing one day ago (present time).

Examples

use utc2k::Utc2k;

assert_eq!(Utc2k::yesterday(), Utc2k::now() - 86_400_u32);

impl Utc2k

String Parsing.

pub fn from_datetime_str<B>(src: B) -> Result<Self, Utc2kError> where
    B: AsRef<[u8]>, 

From Date/Time.

Parse a string containing a date/time in YYYY-MM-DD HH:MM:SS format. This operation is naive and only looks at the positions where numbers are expected.

In other words, 2020-01-01 00:00:00 will parse the same as 2020/01/01 00:00:00 or even 2020-01-01 00:00:00.0000 PDT.

As with all the other methods, dates outside the 2000..=2099 range will be saturated (non-failing), and overflows will be carried over to the appropriate unit (e.g. 13 months will become +1 year and 1 month).

Examples

use utc2k::Utc2k;

// This isn't long enough.
assert!(Utc2k::from_datetime_str("2021/06/25").is_err());

// This is fine.
let date = Utc2k::from_datetime_str("2021-06-25 13:15:25.0000").unwrap();
assert_eq!(date.to_string(), "2021-06-25 13:15:25");

// This is all wrong.
assert!(Utc2k::from_datetime_str("Applebutter").is_err());

Errors

If any of the digits fail to parse, or if the string is insufficiently sized, an error will be returned.

pub fn from_date_str<B>(src: B) -> Result<Self, Utc2kError> where
    B: AsRef<[u8]>, 

From Date/Time.

Parse a string containing a date/time in YYYY-MM-DD format. This operation is naive and only looks at the positions where numbers are expected.

In other words, 2020-01-01 will parse the same as 2020/01/01 or even 2020-01-01 13:03:33.5900 PDT.

As with all the other methods, dates outside the 2000..=2099 range will be saturated (non-failing), and overflows will be carried over to the appropriate unit (e.g. 13 months will become +1 year and 1 month).

The time will always be set to midnight when using this method.

Examples

use utc2k::Utc2k;

// This is fine.
let date = Utc2k::from_date_str("2021/06/25").unwrap();
assert_eq!(date.to_string(), "2021-06-25 00:00:00");

// This is fine, but the time will be ignored.
let date = Utc2k::from_date_str("2021-06-25 13:15:25.0000").unwrap();
assert_eq!(date.to_string(), "2021-06-25 00:00:00");

// This is all wrong.
assert!(Utc2k::from_date_str("Applebutter").is_err());

Errors

If any of the digits fail to parse, or if the string is insufficiently sized, an error will be returned.

pub fn parse_time_str<B>(src: B) -> Result<(u8, u8, u8), Utc2kError> where
    B: AsRef<[u8]>, 

Parse Time.

This method attempts to parse a time string in the HH:MM:SS format, returning the hours, minutes, and seconds as integers.

As with other methods in this library, only positions where numbers are expected will be looked at. 01:02:03 will parse the same way as 01-02-03.

Examples

use utc2k::Utc2k;

assert_eq!(
    Utc2k::parse_time_str("15:35:47"),
    Ok((15, 35, 47))
);

// The hours are out of range.
assert!(Utc2k::parse_time_str("30:35:47").is_err());

Errors

This method will return an error if any of the numeric bits are invalid or out of range (hours must be < 24, minutes and seconds < 60).

impl Utc2k

Get Parts.

pub const fn parts(self) -> (u16, u8, u8, u8, u8, u8)

let date = Utc2k::new(2010, 11, 30, 0, 0, 0);
assert_eq!(date.seconds_from_midnight(), 0);

let date = Utc2k::new(2010, 11, 30, 0, 0, 30);
assert_eq!(date.seconds_from_midnight(), 30);

assert_eq!(date.weekday().as_ref(), "Thursday");

impl Utc2k

Conversion.

pub fn formatted(self) -> FmtUtc2k

Formatted.

This returns a FmtUtc2k and is equivalent to calling FmtUtc2k::from(self).

Examples

use utc2k::{FmtUtc2k, Utc2k};

let date = Utc2k::new(2010, 5, 15, 16, 30, 1);
assert_eq!(date.formatted(), FmtUtc2k::from(date));

pub fn to_rfc3339(&self) -> String

To RFC3339.

Return a string formatted according to RFC3339.

Note: this method is allocating.

Examples

use utc2k::Utc2k;

let date = Utc2k::new(2021, 12, 13, 11, 56, 1);
assert_eq!(date.to_rfc3339(), "2021-12-13T11:56:01Z");

pub fn to_rfc2822(&self) -> String

To RFC2822.

Return a string formatted according to RFC2822.

There are a couple things to consider:

• This method is allocating;
• The length of the resulting string will either be 30 or 31 depending on whether the day is double-digit;

Examples

use utc2k::Utc2k;

let date = Utc2k::new(2003, 7, 1, 10, 52, 37);
assert_eq!(date.to_rfc2822(), "Tue, 01 Jul 2003 10:52:37 +0000");

let date = Utc2k::new(2036, 12, 15, 16, 30, 55);
assert_eq!(date.to_rfc2822(), "Mon, 15 Dec 2036 16:30:55 +0000");

pub fn from_rfc2822<S>(src: S) -> Option<Self> where
    S: AsRef<str>, 

From RFC2822.

This method can be used to construct a Utc2k from an RFC2822-formatted string. Variations with and without a leading weekday, and with and without a trailing offset, are supported. If an offset is included, the datetime will be adjusted accordingly to make it properly UTC.

Note: missing offsets are meant to imply “localized” time, but as this library has no timezone handling, strings without any “+HHMM” at the end will be parsed as if they were already in UTC.

Examples

use utc2k::Utc2k;

assert_eq!(
    Utc2k::from_rfc2822("Tue, 1 Jul 2003 10:52:37 +0000"),
    Some(Utc2k::new(2003, 7, 1, 10, 52, 37)),
);

assert_eq!(
    Utc2k::from_rfc2822("Tue, 01 Jul 2003 10:52:37 +0000"),
    Some(Utc2k::new(2003, 7, 1, 10, 52, 37)),
);

assert_eq!(
    Utc2k::from_rfc2822("1 Jul 2003 10:52:37"),
    Some(Utc2k::new(2003, 7, 1, 10, 52, 37)),
);

assert_eq!(
    Utc2k::from_rfc2822("01 Jul 2003 10:52:37"),
    Some(Utc2k::new(2003, 7, 1, 10, 52, 37)),
);

assert_eq!(
    Utc2k::from_rfc2822("Tue, 10 Jul 2003 10:52:37 -0700"),
    Some(Utc2k::new(2003, 7, 10, 17, 52, 37)),
);

assert_eq!(
    Utc2k::from_rfc2822("Tue, 1 Jul 2003 10:52:37 +0430"),
    Some(Utc2k::new(2003, 7, 1, 6, 22, 37)),
);

pub fn unixtime(self) -> u32

Unix Timestamp.

Return the unix timestamp for this object.

Examples

use utc2k::Utc2k;

let date = Utc2k::default(); // 2000-01-01 00:00:00
assert_eq!(date.unixtime(), Utc2k::MIN_UNIXTIME);

pub fn with_time(self, hh: u8, mm: u8, ss: u8) -> Self

Change Time.

Return a new Utc2k instance with the original date — unless there is carry-over needed — and a new time.

Examples

use utc2k::Utc2k;

let date = Utc2k::default();
assert_eq!(date.to_string(), "2000-01-01 00:00:00");

// Change the time bits.
assert_eq!(date.with_time(13, 14, 15).to_string(), "2000-01-01 13:14:15");

impl Utc2k

Checked Operations.

pub fn checked_add(self, secs: u32) -> Option<Self>

Checked Add.

Return a new Utc2k instance set n seconds into the future from this one, returning none (rather than saturating) on overflow.

If you’d rather saturate addition, you can just use std::ops::Add.

Examples

use utc2k::Utc2k;

let date = Utc2k::max();
assert!(date.checked_add(1).is_none());

let date = Utc2k::new(2010, 1, 1, 0, 0, 0);
let added = date.checked_add(86_413).unwrap();
assert_eq!(added.to_string(), "2010-01-02 00:00:13");

pub fn checked_from_unixtime(src: u32) -> Result<Self, Utc2kError>

From Unixtime (Checked).

This can be used instead of the usual From<u32> if you’d like to trigger an error when the timestamp is out of range (rather than just saturating it).

Errors

An error will be returned if the timestamp is less than Utc2k::MIN_UNIXTIME or greater than Utc2k::MAX_UNIXTIME.

Examples

use utc2k::Utc2k;

// Too old.
assert!(Utc2k::checked_from_unixtime(0).is_err());

// Too new.
assert!(Utc2k::checked_from_unixtime(u32::MAX).is_err());

// This fits.
assert!(Utc2k::checked_from_unixtime(Utc2k::MIN_UNIXTIME).is_ok());

pub fn checked_sub(self, secs: u32) -> Option<Self>

Checked Sub.

Return a new Utc2k instance set n seconds before this one, returning none (rather than saturating) on overflow.

If you’d rather saturate subtraction, you can just use std::ops::Sub.

Examples

use utc2k::Utc2k;

let date = Utc2k::min();
assert!(date.checked_sub(1).is_none());

let date = Utc2k::new(2010, 1, 1, 0, 0, 0);
let subbed = date.checked_sub(86_413).unwrap();
assert_eq!(subbed.to_string(), "2009-12-30 23:59:47");

impl TryFrom<&'_ [u8]> for Utc2k

fn try_from(bytes: &[u8]) -> Result<Self, Self::Error>

Parse Slice.

This will attempt to construct a Utc2k from a date/time or date slice. See Utc2k::from_datetime_str and Utc2k::from_date_str for more information.

Examples

use utc2k::Utc2k;

let date = Utc2k::try_from(&b"2021/06/25"[..]).unwrap();
assert_eq!(date.to_string(), "2021-06-25 00:00:00");

let date = Utc2k::try_from(&b"2021-06-25 13:15:25.0000"[..]).unwrap();
assert_eq!(date.to_string(), "2021-06-25 13:15:25");

assert!(Utc2k::try_from(&b"2021-06-applesauces"[..]).is_err());

type Error = Utc2kError

The type returned in the event of a conversion error.

impl TryFrom<&'_ OsStr> for Utc2k

fn try_from(src: &OsStr) -> Result<Self, Self::Error>

From OsStr.

use std::ffi::OsStr;
use utc2k::Utc2k;

assert_eq!(
    Utc2k::try_from(OsStr::new("2013-12-15 21:30:02")).unwrap().to_string(),
    "2013-12-15 21:30:02"
);
assert_eq!(
    Utc2k::try_from(OsStr::new("2013-12-15")).unwrap().to_string(),
    "2013-12-15 00:00:00"
);

type Error = Utc2kError

The type returned in the event of a conversion error.

impl TryFrom<&'_ str> for Utc2k

fn try_from(src: &str) -> Result<Self, Self::Error>

Parse String.

This will attempt to construct a Utc2k from a date/time or date string. Parsing is naive; only the positions where numbers are expected will be looked at.

String length is used to determine whether or not the value should be parsed as a full date/time (19) or just a date (10).

See Utc2k::from_datetime_str and Utc2k::from_date_str for more information.

Examples

use utc2k::Utc2k;

let date = Utc2k::try_from("2021/06/25").unwrap();
assert_eq!(date.to_string(), "2021-06-25 00:00:00");

let date = Utc2k::try_from("2021-06-25 13:15:25.0000").unwrap();
assert_eq!(date.to_string(), "2021-06-25 13:15:25");

assert!(Utc2k::try_from("2021-06-applesauces").is_err());

type Error = Utc2kError
