Module schedules 

Calculation-period schedule generation.

A Schedule is the ordered list of business-day-adjusted period boundary dates produced from an effective date, a termination date, a frequency, a calendar, a business-day convention, a roll convention, and a stub type.

Structs

Schedule

An ordered set of adjusted calculation-period boundary dates.

Enums

ScheduleError

Why a stated list of boundary dates is not a schedule.

Functions

adjusted 🔒

Business-day-adjusts pts: every boundary but the last by convention, the last by terminal_convention (defaulting to convention), then drops the collisions an adjustment produces — an interior boundary rolled onto or past either end merges into that end, as the two conventions can cross.

advances 🔒

Whether stepping by frequency carries the boundary cursor forward in time.

check_term 🔒

The term runs forwards: effective strictly before termination. Shared by both generators so a reversed or empty term is refused the same way whichever one is called.

generate_backward 🔒

Backward generation, anchored on termination. Each regular boundary is termination − k·frequency measured from the fixed anchor, never from the previously generated boundary (see scale).

generate_forward 🔒

Forward generation, anchored on effective. Each regular boundary is effective + k·frequency measured from the fixed anchor, never from the previously generated boundary (see scale).

negate 🔒

scale 🔒

frequency scaled by k (e.g. 6M, k=2 → 12M), so a generator can march from its fixed anchor by k whole periods rather than from the previous (possibly clamped) boundary.

unadjusted_boundaries 🔒

The unadjusted boundaries from effective to termination: the regular periods measured from one fixed anchor in the direction stub names, the interior roll applied to each before the stop test. Schedule::generate’s core, shared with Schedule::generate_with_stubs.
