There is a separate document on how to contribute to this repo here

Rust-Postgres-Interval is dedicated datatype for the postgres interval type.

extern crate pg_interval;

use pg_interval::Interval;

fn main() {
    let months = 13;
    let days = 1;
    let microseconds = 3600000000;
    let interval = Interval::new(months, days, microseconds);
    let output = interval.to_iso_8601();
    assert_eq!(String::from("P1Y1M1DT1H"), output);
}

• rust 1.22

• Implement method to covert interval into a sql compliant interval string
• Parse iso 8601, postgre, and sql interval strings into interval
• Support for nightly and beta
• Basic chrono integration
