Struct Period 

pub struct Period {
    pub unit: Unit,
    pub start: NaiveDateTime,
}

A calendar-aligned span of local time: one hour, day, ISO week (Mon–Sun) or month.

Fields

unit: Unit

How long the period is.

start: NaiveDateTime

Its first moment, in local time (e.g. Monday 00:00 for a week).

Implementations

impl Period

pub fn containing(unit: Unit, at: NaiveDateTime) -> Self

The period of length unit that contains at.

pub fn current(unit: Unit) -> Self

The period of length unit that contains now.

pub fn end(self) -> NaiveDateTime

The first moment after the period (the start of the next one).

pub fn next(self) -> Self

The following period of the same length.

pub fn prev(self) -> Self

The preceding period of the same length.

pub fn contains(self, at: NaiveDateTime) -> bool

Whether at falls inside the period.

pub fn with_unit(self, unit: Unit) -> Self

Switches unit, staying around “now” if this period contains it.

pub fn bounds(self) -> (DateTime<Local>, DateTime<Local>)

The period as a [start, end) range of local times.

pub fn label(self) -> String

Human-readable name for titles, e.g. week 39 · Sep 21 – Sep 27 2026.

pub fn columns(self) -> Vec<(String, Period)>

Sub-periods used as breakdown columns: days of a week, weeks of a month. Weeks that cross the month edge are included; callers clip them to the month.
