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 an_err Ergonomic constructor and chaining macro for AnErr f Convert a number to the crates Real AnErr A compact, Copy, zero-allocation error type that records a parallel stack
of error kinds, source locations, and per-level human-readable reasons. 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 The library’s central time type. A high-precision instant/duration with attosecond
resolution.Every Builder type that enables the ergonomic start.every(step) syntax. LiteStr Fixed-capacity, stack-only UTF-8 string stored in a single [u8; N] array. ObserverState A snapshot of an observer’s relativistic state at a specific instant. ParseCfg Configuration options for
Dt::from_str_parse 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. StrPTimeFmt A pre-validated, reusable date/time format string. TimeParts A flexible, partially-filled representation of a civil datetime. TimeRange An iterator over evenly spaced Dt 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. YmdHmsRich Gregorian calendar and time-of-day components of a Dt Lang Language codes following ISO 639-1 standard (two-letter codes).

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. Real Alias for f64, maybe upgrade one day
