Structs

  • AtomicInstant
  • Clock
  • ConsistentTimestamp
    Timestamp that tries to be consistent and monotonic across cluster by incorporating node’s unique id and a per-node counter.
  • DateDeprecated
    ISO 8601 calendar date with time zone.
  • DateTime
    ISO 8601 combined date and time with time zone.
  • Duration
    A Duration type to represent a span of time, typically used for system timeouts.
  • FixedOffset
    The time zone with fixed offset, from UTC-23:59:59 to UTC+23:59:59.
  • Instant
    A measurement of a monotonically nondecreasing clock. Opaque and useful only with Duration.
  • Local
    The local timescale. This is implemented via the standard time crate.
  • NaiveDate
    ISO 8601 calendar date without timezone. Allows for every proleptic Gregorian date from Jan 1, 262145 BCE to Dec 31, 262143 CE. Also supports the conversion from ISO 8601 ordinal and week date.
  • NaiveDateTime
    ISO 8601 combined date and time without timezone.
  • NaiveTime
    ISO 8601 time without timezone. Allows for the nanosecond precision and optional leap second representation.
  • SystemTime
    A measurement of the system clock, useful for talking to external entities like the file system or other processes.
  • Utc
    The UTC time zone. This is the most efficient time zone when you don’t need the local time. It is also used as an offset (which is also a dummy type).

Enums

  • Month
    The month of the year.
  • SecondsFormat
    Specific formatting options for seconds. This may be extended in the future, so exhaustive matching in external code is not recommended.
  • Weekday
    The day of week.

Constants

  • UNIX_EPOCH
    An anchor in time which can be used to create new SystemTime instances or learn about where in time a SystemTime lies.

Traits

  • Datelike
    The common set of methods for date component.
  • Offset
    The offset from the local time to UTC.
  • 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.
  • TimeZone
    The time zone.
  • Timelike
    The common set of methods for time component.
