Enums

  An error from rounding by TimeDelta

Traits

• DurationRound
  Extension trait for rounding or truncating a DateTime by a TimeDelta.
• SubsecRound
  Extension trait for subsecond rounding or truncation to a maximum number of digits. Rounding can be used to decrease the error variance when serializing/persisting to lower precision. Truncation is the default behavior in Chrono display formatting. Either can be used to guarantee equality (e.g. for testing) when round-tripping through a lower precision format.
