Struct bonsaidb::core::key::time::limited::LimitedResolutionDuration

pub struct LimitedResolutionDuration<Resolution> where
    Resolution: TimeResolution,  { /* fields omitted */ }

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:

• Weeks
• Days
• Hours
• Minutes
• Seconds
• Milliseconds
• Microseconds
• Nanoseconds

Other resolutions can be used by implementing TimeResolution.
