Macro time::macros::time[−][src]

time!() { /* proc-macro */ }
This is supported on crate feature macros only.
Expand description

Construct a Time with a statically known value.

The resulting expression can be used in const or static declarations.

Hours and minutes must be provided, while seconds defaults to zero. AM/PM is allowed (either uppercase or lowercase). Any number of subsecond digits may be provided (though any past nine will be discarded).

All components are validated at compile-time. An error will be raised if any value is invalid.

assert_eq!(time!("0:00"), Time::from_hms(0, 0, 0)?);
assert_eq!(time!("1:02:03"), Time::from_hms(1, 2, 3)?);

    time!("1:02:03.004_005_006"),
    Time::from_hms_nano(1, 2, 3, 4_005_006)?
);
