Enum otter_api_tests::imports::chrono::LocalResult[−][src]

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

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.
