pub struct Days(/* private fields */);
Expand description
A duration in calendar days.
This is useful because when using TimeDelta
it is possible that adding TimeDelta::days(1)
doesn’t increment the day value as expected due to it being a fixed number of seconds. This
difference applies only when dealing with DateTime<TimeZone>
data types and in other cases
TimeDelta::days(n)
and Days::new(n)
are equivalent.
Implementations§
Trait Implementations§
source§impl<Tz: TimeZone> Add<Days> for DateTime<Tz>
impl<Tz: TimeZone> Add<Days> for DateTime<Tz>
Add Days
to NaiveDateTime
.
§Panics
Panics if:
- The resulting date would be out of range.
- The local time at the resulting date does not exist or is ambiguous, for example during a daylight saving time transition.
Strongly consider using DateTime<Tz>::checked_sub_days
to get an Option
instead.
source§impl Add<Days> for NaiveDate
impl Add<Days> for NaiveDate
Add Days

Panics if the resulting date would be out of range.
Consider using NaiveDate::checked_add_days
to get an Option
instead.
