Struct NdbDateTime 

#[non_exhaustive]
pub struct NdbDateTime {
    pub micros: i64,
}

Microseconds-precision UTC timestamp.

Stores microseconds since Unix epoch as i64. Supports dates from ~292,000 years BCE to ~292,000 years CE.

String format: ISO 8601 "2024-03-15T10:30:00.000000Z".

#[non_exhaustive] — a timezone offset field may be added when named-timezone support is introduced.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

micros: i64

Microseconds since Unix epoch (1970-01-01T00:00:00Z).

Implementations

impl NdbDateTime

pub fn from_micros(micros: i64) -> Self

Create from microseconds since epoch.

pub fn from_millis(millis: i64) -> Result<Self, NdbDateTimeError>

Create from milliseconds since epoch.

Returns Err if millis * 1_000 overflows i64.

pub fn from_secs(secs: i64) -> Result<Self, NdbDateTimeError>

Create from seconds since epoch.

Returns Err if secs * 1_000_000 overflows i64.

pub fn now() -> Self

Current UTC time.

Converts SystemTime microseconds (u128) to i64. Saturates at i64::MAX (year ~292,277 CE) rather than wrapping — clocks that far in the future simply report the maximum representable timestamp.

pub fn components(&self) -> DateTimeComponents

Extract year, month, day, hour, minute, second components.

pub fn to_iso8601(&self) -> String

Format as ISO 8601 string: "2024-03-15T10:30:00.000000Z".

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

Parse from ISO 8601 string (basic subset).

Supports: "2024-03-15T10:30:00Z", "2024-03-15T10:30:00.123456Z", "2024-03-15" (midnight UTC).

pub fn add_duration(&self, d: NdbDuration) -> Result<Self, NdbDateTimeError>

Add a duration.

Returns Err if the result overflows i64.

pub fn sub_duration(&self, d: NdbDuration) -> Result<Self, NdbDateTimeError>

Subtract a duration.

Returns Err if the result overflows i64.

pub fn duration_since( &self, other: &NdbDateTime, ) -> Result<NdbDuration, NdbDateTimeError>

Duration between two timestamps (self - other).

Returns Err if the result overflows i64.

pub fn unix_secs(&self) -> i64

Unix epoch seconds.

pub fn unix_millis(&self) -> i64

Unix epoch milliseconds.
