Rust code to parse dates flexibly with several formats

flexi_data_parse.rs

use chrono::prelude::*;

fn flexi_data_parse(text: &str) -> Option<NaiveDate> {
    let text = text.replace(['.', '/'], "-");

    let fmts = ["%Y-%m-%d", "%Y-%b-%d", "%d-%b-%Y", "%b-%d-%Y", "%d-%m-%Y"];
    for fmt in fmts {
        let parser = NaiveDate::parse_from_str(text.as_str(), fmt);
        if parser.is_ok() {
            return parser.ok();
        }
    }
    None
}

fn main() {
    let dates = [
        "2010-12-11",
        "1999/Mar/02",
        "01.Mar.2021",
        "Mar.05.2021",
        "13/12/1966",
    ];

    for date in dates {
        println!("{:?}", flexi_data_parse(date));
    }
}

Output

Some(2010-12-11)
Some(1999-03-02)
Some(2021-03-01)
Some(2021-03-05)
Some(1966-12-13)
