Implementations

impl UnixNanos

pub const fn new(value: u64) -> Self

Creates a new UnixNanos instance.

pub const fn max() -> Self

Creates a new UnixNanos instance with the maximum valid value.

pub const fn is_zero(&self) -> bool

Returns true if the value of this instance is zero.

pub const fn as_u64(&self) -> u64

Returns the underlying value as u64.

pub const fn as_i64(&self) -> i64

Returns the underlying value as i64.

Panics

Panics if the value exceeds i64::MAX (approximately year 2262).

pub const fn as_f64(&self) -> f64

Returns the underlying value as f64.

pub const fn to_datetime_utc(&self) -> DateTime<Utc>

Converts the underlying value to a datetime (UTC).

Panics

Panics if the value exceeds i64::MAX (approximately year 2262).

pub fn to_rfc3339(&self) -> String

Converts the underlying value to an ISO 8601 (RFC 3339) string.

pub const fn duration_since(&self, other: &Self) -> Option<DurationNanos>

Calculates the duration in nanoseconds since another UnixNanos instance.

Returns Some(duration) if self is later than other, otherwise None if other is greater than self (indicating a negative duration is not possible with DurationNanos).

pub fn checked_add<T: Into<u64>>(self, rhs: T) -> Option<Self>

Returns Some(self + rhs) or None if the addition would overflow

pub fn checked_sub<T: Into<u64>>(self, rhs: T) -> Option<Self>

Returns Some(self - rhs) or None if the subtraction would underflow

pub fn saturating_add_ns<T: Into<u64>>(self, rhs: T) -> Self

Saturating addition – if overflow occurs the value is clamped to u64::MAX.

pub fn saturating_sub_ns<T: Into<u64>>(self, rhs: T) -> Self

Saturating subtraction – if underflow occurs the value is clamped to 0.

Trait Implementations

impl Add<u64> for UnixNanos

Adds a u64 nanosecond value to UnixNanos.

Panics

Panics on overflow. This is intentional fail-fast behavior for timestamp arithmetic. Use UnixNanos::checked_add() for explicit overflow handling.

type Output = UnixNanos

The resulting type after applying the + operator.

fn add(self, rhs: u64) -> Self::Output

Performs the + operation.

impl Add for UnixNanos

Adds two UnixNanos values.

Panics

Panics on overflow. This is intentional fail-fast behavior: overflow in timestamp arithmetic indicates a logic error in calculations that would corrupt data. Use UnixNanos::checked_add() or UnixNanos::saturating_add_ns() if you need explicit overflow handling.

type Output = UnixNanos

The resulting type after applying the + operator.

fn add(self, rhs: Self) -> Self::Output

Performs the + operation.

impl<T: Into<u64>> AddAssign<T> for UnixNanos

Add-assigns a value to UnixNanos.

Panics

Panics on overflow. This is intentional fail-fast behavior for timestamp arithmetic.

fn add_assign(&mut self, other: T)

Performs the += operation.

impl Clone for UnixNanos

fn clone(&self) -> UnixNanos

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UnixNanos

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

Formats the value using the given formatter.

impl Default for UnixNanos

fn default() -> UnixNanos

Returns the “default value” for a type.

impl Deref for UnixNanos

type Target = u64

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'de> Deserialize<'de> for UnixNanos

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

impl Display for UnixNanos

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

Formats the value using the given formatter.

impl From<&str> for UnixNanos

Converts a string slice to UnixNanos.

Panics

This implementation will panic if the string cannot be parsed into a valid UnixNanos. This is intentional fail-fast behavior where invalid timestamps indicate a critical logic error that should halt execution rather than silently propagate incorrect data.

For error handling without panicking, use str::parse::<UnixNanos>() which returns a Result.

let nanos = UnixNanos::from("1234567890");
assert_eq!(nanos.as_u64(), 1234567890);
