Freedom Dates
Let no man put afunder what I believe is thee proper way to shew a written Date. --General George Washington
The freedom-dates
crate provides a convenient suite of affordances for working with dates in
freedom format. That is, it takes representations of dates in Communinst formats like
"2023-02-08", and liberates them into a Freedom format like "2/8/23".
let communism = "2023-02-08T12:00:00-07:00";
let freedom = FreedomDate::liberate(communism).unwrap();
assert_eq!("2/7/23", &result.to_string());
Since Freedom was born on the Fourth of July, 1776 (7/4/76), dates before then are neither valid
nor representable. If you attempt to liberate a date like that, you'll get a
FreedomError::PreCreation
error. Attempts to liberate a date that is too Communist will result
in a FreedomError::TooCommunist
error.
let bad_communism = "Comrade, today is the eighth of Februrary, in the year 2023.";
let pre_history = "1775-07-04";
let too_communist = FreedomDate::liberate(bad_communism).unwrap_err();
let pre_historic_nonsense = FreedomDate::liberate(pre_history).unwrap_err();
println!("'{bad_communism}' is impossible to comprehend: `{too_communist}`\n");
println!("'{pre_history}' is not a real date: `{pre_historic_nonsense}`\n");
will print out:
'Comrade, today is the eighth of Februrary, in the year 2023.' is impossible to comprehend:
I don't speak your crazy Communism-language! 'Comrade, today is the eighth of Februrary, in the year 2023.'
'1775-07-04' is not a real date:
That doesn't hardly make no sense, '1775-07-04' is before the very start of Time/Freedom itself.
A freedomstamp
is the number of seconds since the birth of Freedom, and positive integer values
can be turned into FreedomDates:
// `From<u64>` is implemented for FreedomDates
let birthday_of_freedom: FreedomDate = 0.into();
println!("The Birthday of Freedom is {birthday_of_freedom}\n");
will print
The Birthday of Freedom is 7/4/76
and
let one_day = Duration::days(1);
let day_after_freedom = birthday_of_freedom + one_day;
println!(
"The day after Freedom was born, {day_after_freedom}, {} seconds had passed.",
day_after_freedom.freedomstamp()
);
will print
The day after Freedom was born, 7/5/76, 86400 seconds had passed.
These examples can be found in the tour.
