Struct time::Duration
[-] [+]
[src]
pub struct Duration {
// some fields omitted
}ISO 8601 time duration with nanosecond precision. This also allows for the negative duration; see individual methods for details.
Methods
impl Duration
fn weeks(weeks: i64) -> Duration
Makes a new Duration with given number of weeks.
Equivalent to Duration::seconds(weeks * 7 * 24 * 60 * 60) with overflow checks.
Panics when the duration is out of bounds.
fn days(days: i64) -> Duration
Makes a new Duration with given number of days.
Equivalent to Duration::seconds(days * 24 * 60 * 60) with overflow checks.
Panics when the duration is out of bounds.
fn hours(hours: i64) -> Duration
Makes a new Duration with given number of hours.
Equivalent to Duration::seconds(hours * 60 * 60) with overflow checks.
Panics when the duration is out of bounds.
fn minutes(minutes: i64) -> Duration
Makes a new Duration with given number of minutes.
Equivalent to Duration::seconds(minutes * 60) with overflow checks.
Panics when the duration is out of bounds.
fn seconds(seconds: i64) -> Duration
Makes a new Duration with given number of seconds.
Panics when the duration is more than i64::MAX milliseconds
or less than i64::MIN milliseconds.
fn milliseconds(milliseconds: i64) -> Duration
Makes a new Duration with given number of milliseconds.
fn microseconds(microseconds: i64) -> Duration
Makes a new Duration with given number of microseconds.
fn nanoseconds(nanos: i64) -> Duration
Makes a new Duration with given number of nanoseconds.
fn span<F>(f: F) -> Duration where F: FnOnce()
Runs a closure, returning the duration of time it took to run the closure.
fn num_weeks(&self) -> i64
Returns the total number of whole weeks in the duration.
fn num_days(&self) -> i64
Returns the total number of whole days in the duration.
fn num_hours(&self) -> i64
Returns the total number of whole hours in the duration.
fn num_minutes(&self) -> i64
Returns the total number of whole minutes in the duration.
fn num_seconds(&self) -> i64
Returns the total number of whole seconds in the duration.
fn num_milliseconds(&self) -> i64
Returns the total number of whole milliseconds in the duration,
fn num_microseconds(&self) -> Option<i64>
Returns the total number of whole microseconds in the duration,
or None on overflow (exceeding 263 microseconds in either direction).
fn num_nanoseconds(&self) -> Option<i64>
Returns the total number of whole nanoseconds in the duration,
or None on overflow (exceeding 263 nanoseconds in either direction).
fn checked_add(&self, rhs: &Duration) -> Option<Duration>
Add two durations, returning None if overflow occurred.
fn checked_sub(&self, rhs: &Duration) -> Option<Duration>
Subtract two durations, returning None if overflow occurred.
fn min_value() -> Duration
The minimum possible Duration: i64::MIN milliseconds.
fn max_value() -> Duration
The maximum possible Duration: i64::MAX milliseconds.
fn zero() -> Duration
A duration where the stored seconds and nanoseconds are equal to zero.
fn is_zero(&self) -> bool
Returns true if the duration equals Duration::zero().
