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 Times, they are assumed to be in the same calendar date.

Implementations

Create a Time that is exactly midnight.

assert_eq!(Time::midnight(), time!(0:00));

Attempt to create a Time from the hour, minute, and second.

assert!(Time::try_from_hms(1, 2, 3).is_ok());

Returns None if any component is not valid.

assert!(Time::try_from_hms(24, 0, 0).is_err()); // 24 isn't a valid hour.
assert!(Time::try_from_hms(0, 60, 0).is_err()); // 60 isn't a valid minute.
assert!(Time::try_from_hms(0, 0, 60).is_err()); // 60 isn't a valid second.

This function is const fn when using rustc >= 1.46.

Attempt to create a Time from the hour, minute, second, and millisecond.

assert!(Time::try_from_hms_milli(1, 2, 3, 4).is_ok());

assert!(Time::try_from_hms_milli(0, 60, 0, 0).is_err()); // 60 isn't a valid minute.
assert!(Time::try_from_hms_milli(0, 0, 60, 0).is_err()); // 60 isn't a valid second.
assert!(Time::try_from_hms_milli(0, 0, 0, 1_000).is_err()); // 1_000 isn't a valid millisecond.

assert!(Time::try_from_hms_micro(0, 0, 60, 0).is_err()); // 60 isn't a valid second.
assert!(Time::try_from_hms_micro(0, 0, 0, 1_000_000).is_err()); // 1_000_000 isn't a valid microsecond.

assert!(Time::try_from_hms_nano(0, 0, 60, 0).is_err()); // 60 isn't a valid second.
assert!(Time::try_from_hms_nano(0, 0, 0, 1_000_000_000).is_err()); // 1_000_000_000 isn't a valid nanosecond.
