Function tweetr::util::parse_relative_time

pub fn parse_relative_time(delta: &str) -> Result<Duration, ()>

Parse a relative datetime into a Duration.

This has the form of

• now - current datetime
• in n [second|minute|hour|day|week]{,s} (case-insensitive) - current datetime plus the specified amount of time

Examples

assert_eq!(parse_relative_time("now").unwrap(), Duration::from_secs(0));

assert_eq!(parse_relative_time("in 3 seconds").unwrap(), Duration::from_secs(3));
assert_eq!(parse_relative_time("in 5 MINUTES").unwrap(), Duration::from_secs(60*5));
assert_eq!(parse_relative_time("iN 1 hOur").unwrap(), Duration::from_secs(60*60*1));
assert_eq!(parse_relative_time("in 2 daYs").unwrap(), Duration::from_secs(60*60*24*2));
assert_eq!(parse_relative_time("in 4 weeks").unwrap(), Duration::from_secs(60*60*24*7*4));

assert!(parse_relative_time("in a23d weeks").is_err());
assert!(parse_relative_time("in 23 wsfas1eeks").is_err());
assert!(parse_relative_time("23 wsfas1eeks").is_err());
