log
test bench_add ... bench: 21 ns/iter (+/- 1)
test bench_date_display ... bench: 44 ns/iter (+/- 0)
test bench_date_now_local ... bench: 40 ns/iter (+/- 1)
test bench_date_parse ... bench: 11 ns/iter (+/- 0)
test bench_date_utc ... bench: 39 ns/iter (+/- 1)
test bench_eq ... bench: 0 ns/iter (+/- 0)
it can from_str for any RFC3339
for example:
log
1234_12_13_11_12_13.123456
1234-12-13T11:12:13
1234-12-13 11:12:13.123456
1234-12-13T11:12:13.123456
how use?
rust
use fastdate::DateTime;
fn main(){
//now with local time zone
DateTime::now();
//utc time now
DateTime::utc();
// add
DateTime::now() + Duration::from_secs(1);
// sub
DateTime::now() - Duration::from_secs(1);
//from str
let datetime=DateTime::from_str("1234-12-13 11:12:13.123456");
//to_string()
let s = datetime.to_string();//1234-12-13 11:12:13.123456
}
