Struct Duration 

pub struct Duration {
    pub months: i64,
    pub days: i64,
    pub seconds: i64,
    pub nanos: i32,
}

Calendar/clock duration with month, day, second, and nanosecond components — the model GQL/ISO 8601 uses (months and days are not fixed-length, so they are kept distinct from seconds rather than collapsed). Construct from an ISO 8601 duration string such as P1Y2M10DT2H30M via Duration::parse.

Ordering is structural (months, then days, then seconds, then nanos): a deterministic total order for sorting, not a calendar-normalized comparison.

Fields

months: i64

days: i64

seconds: i64

nanos: i32

Implementations

impl Duration

pub fn parse(value: impl AsRef<str>) -> Result<Self>

Parses an ISO 8601 duration: P[nY][nM][nW][nD][T[nH][nM][nS]]. Years map to 12 months and weeks to 7 days; the seconds field may be fractional (down to nanosecond precision). At least one component is required.

pub fn to_iso_string(&self) -> String

Canonical ISO 8601 string (PT0S for the zero duration).

pub fn checked_add(&self, other: &Self) -> Option<Self>

pub fn negated(&self) -> Self

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 Copy for Duration

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 Eq for Duration

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,

Feeds a slice of this type into the given Hasher.

impl Ord for Duration

fn cmp(&self, other: &Duration) -> 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 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.

impl PartialOrd for Duration

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

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
