Struct Time

pub struct Time {
    pub seconds: SecondsSinceUnixEpoch,
    pub offset: OffsetInSeconds,
    pub sign: Sign,
}

A timestamp with timezone.

Fields

seconds: SecondsSinceUnixEpoch

The seconds that passed since UNIX epoch. This makes it UTC, or <seconds>+0000.

offset: OffsetInSeconds

The time’s offset in seconds, which may be negative to match the sign field.

sign: Sign

the sign of offset, used to encode -0000 which would otherwise lose sign information.

Implementations

impl Time

Formatting

pub fn format(&self, format: impl Into<Format>) -> String

Format this instance according to the given format.

Use Format::Unix, Format::Raw or one of the custom formats defined in the format submodule.

impl Time

Instantiation

pub fn new(seconds: SecondsSinceUnixEpoch, offset: OffsetInSeconds) -> Self

Create a new instance from seconds and offset.

pub fn now_utc() -> Self

Return the current time without figuring out a timezone offset

pub fn now_local() -> Option<Self>

Return the current local time, or None if the local time wasn’t available.

pub fn now_local_or_utc() -> Self

Return the current local time, or the one at UTC if the local time wasn’t available.

impl Time

Serialization with standard git format

pub fn to_bstring(&self) -> BString

Serialize this instance into memory, similar to what write_to() would do with arbitrary Write implementations.

Panics

If the underlying call fails as this instance can’t be represented, typically due to an invalid offset.

pub fn write_to(&self, out: &mut dyn Write) -> Result<()>

Serialize this instance to out in a format suitable for use in header fields of serialized git commits or tags.

pub fn size(&self) -> usize

Computes the number of bytes necessary to write it using Time::write_to().

impl Time

Access

pub fn is_set(&self) -> bool

Return true if this time has been initialized to anything non-default, i.e. 0.

Trait Implementations

impl Clone for Time

fn clone(&self) -> Time

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Time

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

Formats the value using the given formatter.

impl Default for Time

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Time

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Time

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 Time

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

fn eq(&self, other: &Time) -> 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 Time

fn partial_cmp(&self, other: &Time) -> 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.

impl Serialize for Time

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
