time!() { /* proc-macro */ }
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.
