# Enum chrono::offset::LocalResult [−] [src]

    pub enum LocalResult<T> {
        None,
        Single(T),
        Ambiguous(T, T),
    }

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>` [src]

#### `pub fn single(self) -> Option<T>` [src]

Returns `Some` only when the conversion result is unique, or `None` otherwise.

#### `pub fn earliest(self) -> Option<T>` [src]

Returns `Some` for the earliest possible conversion result, or `None` if none.

#### `pub fn latest(self) -> Option<T>` [src]

Returns `Some` for the latest possible conversion result, or `None` if none.

#### `pub fn map<U, F: FnMut(T) -> U>(self, f: F) -> LocalResult<U>` [src]

Maps a `LocalResult<T>` into `LocalResult<U>` with given function.

### `impl<Tz: TimeZone> LocalResult<Date<Tz>>` [src]

#### `pub fn and_time(self, time: NaiveTime) -> LocalResult<DateTime<Tz>>` [src]

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.

#### `pub fn and_hms_opt(
self,
hour: u32,
min: u32,
sec: u32
) -> LocalResult<DateTime<Tz>>` [src]

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.

#### `pub fn and_hms_milli_opt(
self,
hour: u32,
min: u32,
sec: u32,
milli: u32
) -> LocalResult<DateTime<Tz>>` [src]

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.

#### `pub fn and_hms_micro_opt(
self,
hour: u32,
min: u32,
sec: u32,
micro: u32
) -> LocalResult<DateTime<Tz>>` [src]

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.

#### `pub fn and_hms_nano_opt(
self,
hour: u32,
min: u32,
sec: u32,
nano: u32
) -> LocalResult<DateTime<Tz>>` [src]

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.

### `impl<T: Debug> LocalResult<T>` [src]

#### `pub fn unwrap(self) -> T` [src]

Returns the single unique conversion result, or panics accordingly.
