Implement chrono Datetime in jrsonnet as a type so that it can be used in custom jrsonnet methods as a type and can be returned from jrsonnet method as a type

[redoC-A2k]

For example suppose I have a method date
/// Returns current date and time in utc
#[builtin]
fn date(
dateTime: Option,
timeStamp: Option,
year: Option,
monthIndex: Option,
day: Option,
hours: Option,
minutes: Option,
seconds: Option,
milliseconds: Option,
)
Now I want to return chrono::Datetime from above method and then in another method suppose ,
#[builtin]
fn format_date
I want to take chrono::Datetime object/struct as argument and return string .

Please could you provide help ?

I don't quite understand what do you want. Provide Typed implementation for chrono::Datetime, which will automatically convert it to String for jsonnet code, and back?
