Struct PublishTime 

pub struct PublishTime(/* private fields */);

A release publish instant, normalized to Unix epoch seconds (UTC).

Copy and cheap to pass around, so it fits into Box<dyn Version> trait objects without lifetime or allocation concerns.

Examples

use deps_core::PublishTime;

let published = PublishTime::parse_rfc3339("2026-07-18T23:05:13Z").unwrap();
let now = PublishTime::from_unix_secs(published.as_unix_secs() + 3600);

assert_eq!(published.age_secs_from(now), 3600);

Implementations

impl PublishTime

pub fn now() -> Self

Returns the current time as a PublishTime.

Uses std::time::SystemTime rather than the time crate’s own “now” APIs, so this module never needs the local-offset/ wasm-bindgen features. A clock before the Unix epoch saturates to 0.

Examples

use deps_core::PublishTime;

let now = PublishTime::now();
assert!(now.as_unix_secs() > 0);

pub const fn from_unix_secs(secs: i64) -> Self

Builds a PublishTime directly from Unix epoch seconds.

Examples

use deps_core::PublishTime;

let t = PublishTime::from_unix_secs(1_753_052_713);
assert_eq!(t.as_unix_secs(), 1_753_052_713);

pub fn parse_rfc3339(s: &str) -> Option<Self>

Parses an RFC 3339 timestamp string into a PublishTime.

Accepts every shape seen across v1 registries: a bare Z suffix, arbitrary fractional-second digits, and a numeric UTC offset (+00:00). Returns None on any parse failure — per US-003, a missing or malformed timestamp degrades to pre-feature behavior rather than surfacing an error.

Examples

use deps_core::PublishTime;

assert!(PublishTime::parse_rfc3339("2026-07-18T23:05:13Z").is_some());
assert!(PublishTime::parse_rfc3339("2026-05-14T19:25:27.735762Z").is_some());
assert!(PublishTime::parse_rfc3339("2026-01-02T08:56:05+00:00").is_some());
assert!(PublishTime::parse_rfc3339("not a timestamp").is_none());
assert!(PublishTime::parse_rfc3339("").is_none());

pub const fn as_unix_secs(self) -> i64

Returns this instant as Unix epoch seconds.

Examples

use deps_core::PublishTime;

let t = PublishTime::from_unix_secs(42);
assert_eq!(t.as_unix_secs(), 42);

pub const fn age_secs_from(self, now: Self) -> u64

Age of this publish instant relative to now, in seconds.

A self in the future relative to now (clock skew, or a registry timestamp bug) saturates to age 0 rather than underflowing or returning a negative duration — chosen because a slightly-ahead registry clock is exactly the “just published” case the freshness signal exists to surface, so clamping preserves the signal instead of silently losing it.

Examples

use deps_core::PublishTime;

let published = PublishTime::from_unix_secs(1_000);
let now = PublishTime::from_unix_secs(1_100);
assert_eq!(published.age_secs_from(now), 100);

// Clock skew: published "after" now clamps to 0, not a negative age.
let future = PublishTime::from_unix_secs(2_000);
assert_eq!(future.age_secs_from(now), 0);

Trait Implementations

impl Clone for PublishTime

fn clone(&self) -> PublishTime

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for PublishTime

impl Debug for PublishTime

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for PublishTime

impl Ord for PublishTime

fn cmp(&self, other: &PublishTime) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for PublishTime

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for PublishTime

fn partial_cmp(&self, other: &PublishTime) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
