}Parsed parts of date and time. There are two classes of methods:
set_*methods try to set given field(s) while checking for the consistency. It may or may not check for the range constraint immediately (for efficiency reasons).to_*methods try to make a concrete date and time value out of set fields. It fully checks any remaining out-of-range conditions and inconsistent/impossible fields,
Fields
year | Year. This can be negative unlike |
year_div_100 | Year divided by 100. Implies that the year is >= 1 BCE when set. Due to the common usage, if this field is missing but |
year_mod_100 | Year modulo 100. Implies that the year is >= 1 BCE when set. |
isoyear | Year in the ISO week date. This can be negative unlike |
isoyear_div_100 | Year in the ISO week date, divided by 100. Implies that the year is >= 1 BCE when set. Due to the common usage, if this field is missing but |
isoyear_mod_100 | Year in the ISO week date, modulo 100. Implies that the year is >= 1 BCE when set. |
month | Month (1--12). |
week_from_sun | Week number, where the week 1 starts at the first Sunday of January. (0--53, 1--53 or 1--52 depending on the year). |
week_from_mon | Week number, where the week 1 starts at the first Monday of January. (0--53, 1--53 or 1--52 depending on the year). |
isoweek | ISO week number (1--52 or 1--53 depending on the year). |
weekday | Day of the week. |
ordinal | Day of the year (1--365 or 1--366 depending on the year). |
day | Day of the month (1--28, 1--29, 1--30 or 1--31 depending on the month). |
hour_div_12 | Hour number divided by 12 (0--1). 0 indicates AM and 1 indicates PM. |
hour_mod_12 | Hour number modulo 12 (0--11). |
minute | Minute number (0--59). |
second | Second number (0--60, accounting for leap seconds). |
nanosecond | The number of nanoseconds since the whole second (0--999,999,999). |
timestamp | The number of non-leap seconds since January 1, 1970 0:00:00 UTC. This can be off by one if |
offset | Offset from the local time to UTC, in seconds. |
Methods
impl Parsed
fn new() -> Parsed
Returns the initial value of parsed parts.
fn set_year(&mut self, value: i64) -> ParseResult<()>
Tries to set the year field from given value.
fn set_year_div_100(&mut self, value: i64) -> ParseResult<()>
Tries to set the year_div_100 field from given value.
fn set_year_mod_100(&mut self, value: i64) -> ParseResult<()>
Tries to set the year_mod_100 field from given value.
fn set_isoyear(&mut self, value: i64) -> ParseResult<()>
Tries to set the isoyear field from given value.
fn set_isoyear_div_100(&mut self, value: i64) -> ParseResult<()>
Tries to set the isoyear_div_100 field from given value.
fn set_isoyear_mod_100(&mut self, value: i64) -> ParseResult<()>
Tries to set the isoyear_mod_100 field from given value.
fn set_month(&mut self, value: i64) -> ParseResult<()>
Tries to set the month field from given value.
fn set_week_from_sun(&mut self, value: i64) -> ParseResult<()>
Tries to set the week_from_sun field from given value.
fn set_week_from_mon(&mut self, value: i64) -> ParseResult<()>
Tries to set the week_from_mon field from given value.
fn set_isoweek(&mut self, value: i64) -> ParseResult<()>
Tries to set the isoweek field from given value.
fn set_weekday(&mut self, value: Weekday) -> ParseResult<()>
Tries to set the weekday field from given value.
fn set_ordinal(&mut self, value: i64) -> ParseResult<()>
Tries to set the ordinal field from given value.
fn set_day(&mut self, value: i64) -> ParseResult<()>
Tries to set the day field from given value.
fn set_ampm(&mut self, value: bool) -> ParseResult<()>
Tries to set the hour_div_12 field from given value. (false for AM, true for PM)
fn set_hour12(&mut self, value: i64) -> ParseResult<()>
Tries to set the hour_mod_12 field from given hour number in 12-hour clocks.
fn set_hour(&mut self, value: i64) -> ParseResult<()>
Tries to set both hour_div_12 and hour_mod_12 fields from given value.
fn set_minute(&mut self, value: i64) -> ParseResult<()>
Tries to set the minute field from given value.
fn set_second(&mut self, value: i64) -> ParseResult<()>
Tries to set the second field from given value.
fn set_nanosecond(&mut self, value: i64) -> ParseResult<()>
Tries to set the nanosecond field from given value.
fn set_timestamp(&mut self, value: i64) -> ParseResult<()>
Tries to set the timestamp field from given value.
fn set_offset(&mut self, value: i64) -> ParseResult<()>
Tries to set the offset field from given value.
fn to_naive_date(&self) -> ParseResult<NaiveDate>
Returns a parsed naive date out of given fields.
This method is able to determine the date from given subset of fields:
- Year, month, day.
- Year, day of the year (ordinal).
- Year, week number counted from Sunday or Monday, day of the week.
- ISO week date.
Gregorian year and ISO week date year can have their century number (*_div_100) omitted,
the two-digit year is used to guess the century number then.
fn to_naive_time(&self) -> ParseResult<NaiveTime>
Returns a parsed naive time out of given fields.
This method is able to determine the time from given subset of fields:
- Hour, minute. (second and nanosecond assumed to be 0)
- Hour, minute, second. (nanosecond assumed to be 0)
- Hour, minute, second, nanosecond.
It is able to handle leap seconds when given second is 60.
fn to_naive_datetime_with_offset(&self, offset: i32) -> ParseResult<NaiveDateTime>
Returns a parsed naive date and time out of given fields,
except for the offset field (assumed to have a given value).
This is required for parsing a local time or other known-timezone inputs.
This method is able to determine the combined date and time
from date and time fields or a single timestamp field.
Either way those fields have to be consistent to each other.
fn to_fixed_offset(&self) -> ParseResult<FixedOffset>
Returns a parsed fixed time zone offset out of given fields.
fn to_datetime(&self) -> ParseResult<DateTime<FixedOffset>>
Returns a parsed timezone-aware date and time out of given fields.
This method is able to determine the combined date and time
from date and time fields or a single timestamp field, plus a time zone offset.
Either way those fields have to be consistent to each other.
fn to_datetime_with_timezone<Tz: TimeZone>(&self, tz: &Tz) -> ParseResult<DateTime<Tz>>
Returns a parsed timezone-aware date and time out of given fields,
with an additional TimeZone used to interpret and validate the local date.
This method is able to determine the combined date and time
from date and time fields or a single timestamp field, plus a time zone offset.
Either way those fields have to be consistent to each other.
If parsed fields include an UTC offset, it also has to be consistent to offset.
