Add more calendars.

[avhz]

This just involves going through each country and completing the following boilerplate (using some source such as timeanddate.com).

pub struct Argentina;

impl Calendar for Argentina {
    fn name(&self) -> &'static str {
        "Argentina"
    }

    fn country_code(&self) -> crate::iso::ISO_3166 {
        crate::iso::ARGENTINA
    }

    // Use the MIC code for the primary stock exchange of the country.
    fn market_identifier_code(&self) -> crate::iso::ISO_10383 {
        crate::iso::XBUE
    }

    fn is_business_day(&self, date: OffsetDateTime) -> bool {
        let (w, d, m, y, dd) = self.unpack_date(date);
        let em = Self::easter_monday(y as usize, false);

        if Self::is_weekend(date)
            || (d == 25 && m == Month::December)  // Christmas
            || (d == 1 && m == Month::January)    // New Years Day
             ...                                  // and so on...
        {
            return false;
        }

        true
    }
}

[avhz]

Sure :) take a look at what is already implemented for an idea of what needs to be done.

Thanks for your interest !

Hi, I'm not getting that error. Looks like a problem with the plotters crate.

Is your Rust up-to-date? Try rustup update and re-compile and let me know what happens.

Edit: probably also worth running cargo clean after updating Rust.

Hi thanks @avhz I'm able to build now but how to run this locally getting this.

dakshdagariya@Dakshs-MacBook-Air RustQuant % cargo run            
error: a bin target must be available for `cargo run`

[avhz]

RustQuant is a library, not a binary. So you can't run it.

You may find the Rust book helpful: https://doc.rust-lang.org/book/

I believe there's a chapter about libraries and binaries.

okay thanks a lot.
