tzdb

This module is auto-generated from the IANA Time Zone Database found at: https://www.iana.org/time-zones Source directory: tzdata2026a It provides both a minimal mode (UTC + identical zones only) and a full mode (tz feature) which has full historical transitions. Generator source: https://github.com/ragardner/tz-info-generator-rs

Macros

an_err

Ergonomic constructor and chaining macro for AnErr.

f

Convert a number to the crates Real type (f64).

Structs

AnErr

A compact, Copy, zero-allocation error type that records a parallel stack of error kinds, source locations, and per-level human-readable reasons.

AsciiStr

Fixed-capacity, stack-only ASCII string stored in a single [u8; N] array.

ClockModel

A fully self-describing custom relativistic time scale.

Drift

Quadratic polynomial that describes the accumulated difference between an observer’s proper time (the time measured by a real clock moving through spacetime) and a chosen coordinate time such as TT, TAI, or any other Scale.

Dt

Dt, and the library, is in the process of being switched from the sec and subsec fields being related to the scale, TO the sec and subsec fields always being TAI Epoch 2000-01-01 noon. Much of the documentation is outdated and should be ignored.

Every

Builder type that enables the ergonomic start.every(step) syntax.

GregorianTime

UTC Civil calendar and time-of-day components of a Dt.

ObserverState

A snapshot of an observer’s relativistic state at a specific instant.

ParseCfg

Position

A 3-dimensional position vector expressed in Cartesian coordinates (x, y, z) with units of meters (SI).

Spacetime

The three local spacetime quantities that fully determine how fast an observer’s proper time advances relative to coordinate time.

TimeParts

A flexible, partially-filled representation of a civil datetime.

TimeRange

An iterator over evenly spaced Dt values.

Velocity

A 3-dimensional velocity vector expressed in Cartesian coordinates (vx, vy, vz) with units of meters per second (SI).

WireErr

Fully portable, zero-allocation error for transmission/reception.

WireLocation

Portable location for wire transmission.

YmdHms

Combined Gregorian date + wall time with subsecond precision.

Enums

AsciiStrError

Errors returned by AsciiStr operations.

DateOrder

DateParseMode

Only relevant for purely numeric dates.

Lang

Language codes following ISO 639-1 standard (two-letter codes) Default is En (English)

Meridiem

AM / PM indicator.

Offset

Timezone offset representation.

Scale

Time scales supported for conversions.

Weekday

Day of the week. Default is set to Sunday.

Traits

AttosTraits

Trait that adds ergonomic conversions from attoseconds values for i64, i128, and f64.

TimeTraits

Trait that adds ergonomic time-unit methods to integers and floats.

Functions

to_fs
