Struct chrono::naive::Days

source ·
pub struct Days(/* private fields */);
Expand description

A duration in calendar days.

This is useful because when using Duration it is possible that adding Duration::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 Duration::days(n) and Days::new(n) are equivalent.
