Struct sqlx::types::time::Time [−]
pub struct Time { /* fields omitted */ }
Expand description
The clock time within a given date. Nanosecond precision.
All minutes are assumed to have exactly 60 seconds; no attempt is made to handle leap seconds (either positive or negative).
When comparing two Time
s, they are assumed to be in the same calendar
date.
