pub struct LimitedResolutionDuration<Resolution: TimeResolution> { /* private fields */ }
Expand description

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.

Converting from Duration truncates the duration and performs no rounding.

The Resolution type controls the storage size. The resolutions provided by BonsaiDb:

Other resolutions can be used by implementing TimeResolution.
