wasm-friendly Datetime utility crate about seed HOT 4 CLOSED

Is there any reason this can't be added to chrono? Have they rejected the idea of having a web submodule which is enabled by a feature?

from seed.

That might be the best approach. Not rejected, but there's a related issue and PR that's been idle for a bit. Worth pursuing this route.

I'm still concerned about the verbosity of the api; ie I don't want users to have to write code like this wrapper:

    /// Convert an iso-format date, eg "2019-01-05" for January 5, 2019" to a Date.
    pub fn from_iso(date: &str) -> Self {
        // Chrono needs time too; and can't parse date-only directly.
        let padded = &(date.to_string() + "T000000");
        Self {
            wrapped: chrono::Utc
                .datetime_from_str(padded, "%Y-%m-%dT%H%M%S")
                .expect(&format!("Can't format date: {}", date))
                .date()
        }
    }

Although this could also be a PR for Chrono.

I would expect a function called from_iso to fully support all of ISO, not just dates. So that seems like an ad-hoc function specialized to a particular app's needs.

Aside from that, is chrono::DateTime::parse_from_rfc3339(date).unwrap_throw().date() too verbose? It seems pretty straightforward to me, personally.

And similarly, a chrono::Date::parse_from_rfc3339(date).unwrap_throw() could be used for date only (though that needs a PR to add it to chrono).

from seed.

Closing this for now - until I find the scope of limitations of Chrono in WASM, and pursue PRs there.
