}
Expand description
Value of an IntervalMonthDayNano array
§Representation
This type is stored as a single 128 bit integer, interpreted as three different signed integral fields:
- The number of months (32 bits)
- The number days (32 bits)
- The number of nanoseconds (64 bits).
Nanoseconds does not allow for leap seconds.
Each field is independent (e.g. there is no constraint that the quantity of nanoseconds represents less than a day’s worth of time).
┌───────────────┬─────────────┬─────────────────────────────┐
│ Months │ Days │ Nanos │

§Note on Comparing and Ordering for Calendar Types
Values of IntervalMonthDayNano
are compared using their binary
representation, which can lead to surprising results.
Spans of time measured in calendar units are not fixed in absolute size (e.g.
number of seconds) which makes defining comparisons and ordering non trivial.
For example 1 month
is 28 days for February but 1 month
is 31 days
in December.
This makes the seemingly simple operation of comparing two intervals
complicated in practice. For example is 1 month
more or less than 30 days
? The answer depends on what month you are talking about.
This crate defines comparisons for calendar types using their binary representation which is fast and efficient, but leads to potentially surprising results.
For example a
IntervalMonthDayNano
of 1 month
will compare as greater than a
IntervalMonthDayNano
of 100 days
because the binary representation of 1 month
is larger than the binary representation of 100 days.
