Struct Time

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

Time is as the number of nanoseconds since the Unix epoch. The default value of Time is the Unix epoch 1970-01-01 00:00:00 UTC. This default may not be suitable for all applications, so wrap time in an Option.

Implementations

impl Time

pub const fn from_unix_nanos(time: i128) -> Time

Constructs a time instance with nanoseconds since the Unix epoch.

pub const fn from_unix_secs(time: i64) -> Time

Constructs a time instance with seconds since the Unix epoch.

pub const fn unix_nanos(&self) -> i128

Returns the number of nanoseconds since the Unix epoch.

pub const fn add(self, duration: Duration) -> Time

Adds a duration to the time.

pub const fn sub(self, duration: Duration) -> Time

Subtracts a duration from the time.

pub const fn since(self, time: Time) -> Duration

Returns the duration elapsed since the other time.

pub const fn until(self, time: Time) -> Duration

Returns the duration until the other time.

Trait Implementations

impl ObjectFieldValue for Time

type In<'a> = Time

The type that is used when inputting object values to functions.

type Out<'a> = Time

The type that is used in function return values.

impl Ord for Time

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

This method returns an Ordering between self and other.

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