Implementations

impl DateTimeField

pub fn next_smallest(self) -> Self

Iterate the DateTimeField to the next value.

Panics

• When called on Second

pub fn next_largest(self) -> Self

Iterate the DateTimeField to the prior value.

Panics

• When called on Year

pub fn seconds_multiplier(self) -> i64

Returns the number of seconds in a single unit of field.

Panics

Panics if called on a non-duration field or a field smaller than a second.

pub fn seconds_divider(self) -> i64

Returns the number of ‘fields’ in a single second.

Panics

Panics if called on a non-duration field or a field larger than or equal to a second.

pub fn nanos_multiplier(self) -> i64

Returns the number of nanoseconds in a single unit of field.

Panics

Panics if called on a non-duration field or a field smaller than a nanosecond.

pub fn month_multiplier(self) -> i64

Returns the number of months in a single unit of field.

Panics

Panics if called on a duration field.
