Module bonsaidb_core::key::time::limited

Types for storing limited-precision Durations.

Structs

• BonsaiEpoch
  A TimeEpoch implementation that allows storing LimitedResolutionTimestamp relative to the 10-year anniversary of BonsaiDb: March 20, 2031 04:31:47 UTC.
• LimitedResolutionDuration
  A Duration of time stored with a limited Resolution. This type may be preferred to std::time::Duration because Duration takes a full 12 bytes to achieve its nanosecond resolution.
• LimitedResolutionTimestamp
  A timestamp (moment in time) stored with a limited Resolution. This type may be preferred to std::time::SystemTime because SystemTime serializes with nanosecond resolution. Often this level of precision is not needed and less storage and memory can be used.
• UnixEpoch
  A TimeEpoch implementation that allows storing LimitedResolutionTimestamp relative to the “unix epoch”: January 1, 1970 00:00:00 UTC.

Enums

• Days
  A TimeResolution implementation that truncates time measurements to days. Internally, the number of days is represented as an i32, allowing a range of +/- ~5.88 million years.
• Hours
  A TimeResolution implementation that truncates time measurements to hours. Internally, the number of hours is represented as an i32, allowing a range of +/- ~245,147 years.
• Microseconds
  A TimeResolution implementation that truncates time measurements to microseconds. Internally, the number of microseconds is represented as an i64, allowing a range of +/- ~292,471 years.
• Milliseconds
  A TimeResolution implementation that truncates time measurements to milliseconds. Internally, the number of milliseconds is represented as an i64, allowing a range of +/- ~292.5 million years.
• Minutes
  A TimeResolution implementation that truncates time measurements to minutes. Internally, the number of minutes is represented as an i32, allowing a range of +/- ~4,086 years.
• Nanoseconds
  A TimeResolution implementation that preserves nanosecond resolution. Internally, the number of microseconds is represented as an i64, allowing a range of +/- ~292.5 years.
• Seconds
  A TimeResolution implementation that truncates time measurements to seconds. Internally, the number of seconds is represented as an i64, allowing a range of +/- ~21 times the age of the universe.
• SignedDuration
  A Duration that can be either negative or positive.
• Weeks
  A TimeResolution implementation that truncates time measurements to weeks. Internally, the number of weeks is represented as an i32, allowing a range of +/- ~41.18 million years.

Traits

• AnyTimestamp
  A timestamp that can report it sduration since the Unix Epoch.
• TimeEpoch
  An epoch for LimitedResolutionTimestamp.
• TimeResolution
  A resolution of a time measurement.
