Struct Duration 

pub struct Duration { /* private fields */ }

An ISO 8601 duration with separate month, day, and nanosecond components.

The three components are kept separate because months have variable length and cannot be converted to days without a reference date. This means durations are only partially ordered.

Examples

use grafeo_common::types::Duration;

let d = Duration::parse("P1Y2M3DT4H5M6S").unwrap();
assert_eq!(d.months(), 14); // 1 year + 2 months
assert_eq!(d.days(), 3);
assert_eq!(d.to_string(), "P1Y2M3DT4H5M6S");

Implementations

impl Duration

pub const fn new(months: i64, days: i64, nanos: i64) -> Self

Creates a duration from months, days, and nanoseconds.

pub const fn from_months(months: i64) -> Self

Creates a duration from a number of months.

pub const fn from_days(days: i64) -> Self

Creates a duration from a number of days.

pub const fn from_nanos(nanos: i64) -> Self

Creates a duration from nanoseconds.

pub const fn from_seconds(secs: i64) -> Self

Creates a duration from seconds.

pub const fn months(&self) -> i64

Returns the months component.

pub const fn days(&self) -> i64

Returns the days component.

pub const fn nanos(&self) -> i64

Returns the nanoseconds component.

pub const fn is_zero(&self) -> bool

Returns true if all components are zero.

pub const fn neg(self) -> Self

Negates all components.

pub const fn add(self, other: Self) -> Self

Adds two durations component-wise.

pub const fn sub(self, other: Self) -> Self

Subtracts another duration component-wise.

pub const fn mul(self, factor: i64) -> Self

Multiplies all components by a factor.

pub const fn div(self, divisor: i64) -> Self

Divides all components by a divisor (truncating).

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

Parses a duration from ISO 8601 format “OnYnMnDTnHnMnS”.

Examples: “P1Y”, “P2M3D”, “PT4H5M6S”, “P1Y2M3DT4H5M6S”, “PT0.5S”

Trait Implementations

impl Clone for Duration

fn clone(&self) -> Duration

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Duration

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

Formats the value using the given formatter.

impl Default for Duration

fn default() -> Duration

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Duration

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Duration

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

Formats the value using the given formatter.

impl From<Duration> for Value

fn from(d: Duration) -> Self

Converts to this type from the input type.

impl Hash for Duration

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,

impl PartialEq for Duration

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
