Struct Timestamp 

pub struct Timestamp {
    pub datetime: DateTime<Utc>,
    pub precision: TemporalPrecision,
}

A timestamp with timezone awareness and precision tracking.

Timestamps in spatial narratives often come from sources with varying precision (e.g., “sometime in March 2024” vs “2024-03-15T14:30:00Z”).

Examples

use spatial_narrative::core::{Timestamp, TemporalPrecision};

// Current time
let now = Timestamp::now();

// Parse from ISO 8601
let ts = Timestamp::parse("2024-03-15T14:30:00Z").unwrap();

// With explicit precision
let approximate = Timestamp::with_precision(
    Timestamp::parse("2024-03-01T00:00:00Z").unwrap().datetime,
    TemporalPrecision::Month
);

Fields

datetime: DateTime<Utc>

The datetime in UTC.

precision: TemporalPrecision

The precision of this timestamp.

Implementations

impl Timestamp

pub fn new(datetime: DateTime<Utc>) -> Self

Creates a new timestamp with the given datetime and default (Second) precision.

pub fn with_precision( datetime: DateTime<Utc>, precision: TemporalPrecision, ) -> Self

Creates a new timestamp with explicit precision.

pub fn now() -> Self

Creates a timestamp for the current moment.

pub fn parse(s: &str) -> Result<Self>

Parses a timestamp from an ISO 8601 string.

Supported formats:

• 2024-03-15T14:30:00Z (full precision)
• 2024-03-15T14:30:00+00:00 (with timezone offset)
• 2024-03-15 (date only, day precision)
• 2024-03 (year-month, month precision)
• 2024 (year only, year precision)

pub fn from_unix(secs: i64) -> Option<Self>

Creates a timestamp from Unix epoch seconds.

pub fn from_unix_millis(millis: i64) -> Option<Self>

Creates a timestamp from Unix epoch milliseconds.

pub fn unix_timestamp(&self) -> i64

Returns the Unix timestamp in seconds.

pub fn unix_timestamp_millis(&self) -> i64

Returns the Unix timestamp in milliseconds.

pub fn to_unix_millis(&self) -> i64

Returns the Unix timestamp in milliseconds (alias for unix_timestamp_millis).

pub fn to_rfc3339(&self) -> String

Formats the timestamp as an ISO 8601 string.

pub fn format_with_precision(&self) -> String

Formats the timestamp according to precision.

pub fn is_before(&self, other: &Timestamp) -> bool

Checks if this timestamp is before another.

pub fn is_after(&self, other: &Timestamp) -> bool

Checks if this timestamp is after another.

pub fn duration_since(&self, earlier: &Timestamp) -> Duration

Returns the duration between this timestamp and another.

Trait Implementations

impl Clone for Timestamp

fn clone(&self) -> Timestamp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Timestamp

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

Formats the value using the given formatter.

impl Default for Timestamp

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Timestamp

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Timestamp

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

Formats the value using the given formatter.

impl From<DateTime<Utc>> for Timestamp

fn from(datetime: DateTime<Utc>) -> Self

Converts to this type from the input type.

impl Hash for Timestamp

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Timestamp

fn cmp(&self, other: &Self) -> 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,

impl PartialEq for Timestamp

fn eq(&self, other: &Timestamp) -> 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.

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.

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Timestamp
