Enum chrono::offset::LocalResult
source · [−]pub enum LocalResult<T> {
None,
Single(T),
Ambiguous(T, T),
}
Expand description
The conversion result from the local time to the timezone-aware datetime types.
Variants
None
Given local time representation is invalid. This can occur when, for example, the positive timezone transition.
Single(T)
Given local time representation has a single unique result.
Ambiguous(T, T)
Given local time representation has multiple results and thus ambiguous. This can occur when, for example, the negative timezone transition.
Implementations

impl<T> LocalResult<T>
sourcepub fn single(self) -> Option<T>
pub fn single(self) -> Option<T>
Returns Some
only when the conversion result is unique, or None
otherwise.
sourcepub fn earliest(self) -> Option<T>
pub fn earliest(self) -> Option<T>
Returns Some
for the earliest possible conversion result, or None
if none.
sourcepub fn latest(self) -> Option<T>
pub fn latest(self) -> Option<T>
Returns Some
for the latest possible conversion result, or None
if none.
sourcepub fn map<U, F: FnMut(T) -> U>(self, f: F) -> LocalResult<U>
pub fn map<U, F: FnMut(T) -> U>(self, f: F) -> LocalResult<U>
Maps a LocalResult<T>
into LocalResult<U>
with given function.

impl<Tz: TimeZone> LocalResult<Date<Tz>>
sourcepub fn and_time(self, time: NaiveTime) -> LocalResult<DateTime<Tz>>
pub fn and_time(self, time: NaiveTime) -> LocalResult<DateTime<Tz>>
Makes a new DateTime
from the current date and given NaiveTime
.
The offset in the current date is preserved.
Propagates any error. Ambiguous result would be discarded.
sourcepub fn and_hms_opt(
self,
hour: u32,
min: u32,
sec: u32
) -> LocalResult<DateTime<Tz>>
pub fn and_hms_opt(
self,
hour: u32,
min: u32,
sec: u32
) -> LocalResult<DateTime<Tz>>
Makes a new DateTime
from the current date, hour, minute and second.
The offset in the current date is preserved.
Propagates any error. Ambiguous result would be discarded.
sourcepub fn and_hms_milli_opt(
self,
hour: u32,
min: u32,
sec: u32,
milli: u32
) -> LocalResult<DateTime<Tz>>
pub fn and_hms_milli_opt(
self,
hour: u32,
min: u32,
sec: u32,
milli: u32
) -> LocalResult<DateTime<Tz>>
Makes a new DateTime
from the current date, hour, minute, second and millisecond.
The millisecond part can exceed 1,000 in order to represent the leap second.
The offset in the current date is preserved.
Propagates any error. Ambiguous result would be discarded.
sourcepub fn and_hms_micro_opt(
self,
hour: u32,
min: u32,
sec: u32,
micro: u32
) -> LocalResult<DateTime<Tz>>
pub fn and_hms_micro_opt(
self,
hour: u32,
min: u32,
sec: u32,
micro: u32
) -> LocalResult<DateTime<Tz>>
Makes a new DateTime
from the current date, hour, minute, second and microsecond.
The microsecond part can exceed 1,000,000 in order to represent the leap second.
The offset in the current date is preserved.
Propagates any error. Ambiguous result would be discarded.
sourcepub fn and_hms_nano_opt(
self,
hour: u32,
min: u32,
sec: u32,
nano: u32
) -> LocalResult<DateTime<Tz>>
pub fn and_hms_nano_opt(
self,
hour: u32,
min: u32,
sec: u32,
nano: u32
) -> LocalResult<DateTime<Tz>>
Makes a new DateTime
from the current date, hour, minute, second and nanosecond.
The nanosecond part can exceed 1,000,000,000 in order to represent the leap second.
The offset in the current date is preserved.
Propagates any error. Ambiguous result would be discarded.
