This package allows to get a time.Duration from a string. The string can be a string retorned for time.Duration or a similar string with weeks or days too!.
go get github.com/xhit/go-str2durationGo String To Duration supports this strings conversions to duration:
- All strings returned in time.Duration String.
- A string more readable like 1w2d6h3ns (1 week 2 days 6 hours and 3 nanoseconds).
µsandusare microsecond.
Note: a day is 24 hour.
If you don't need days and weeks, use time.ParseDuration.
- Imagine you save the output of time.Duration strings in a database, file, etc... and you need to convert again to time.Duration. Now you can!
- Set a more precise duration in a configuration file for wait, timeouts, measure, etc...
