Macro time

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

Available on crate feature macros only.

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.
