How do I send a Foo/get request?

[WhyNotHugo]

I'm trying to implement a JMAP client to synchronise calendars on a JMAP server. I'm basing my work on the current JMAP calendar draft.

I can't figure out how to use this library to execute a Foo/get request (e.g.: as described in rfc8620#section-5.1).

Do you have any pointers or examples or references that might help here? I've looked at jmap_client::core::get and jmap_client::Get, but I don't quite understand how these are meant to be used.

The Foo object does not exist in JMAP, it is used to demonstrate how the /get method works.

[WhyNotHugo]

I understand that Foo is an example/placeholder, and it is used with the same intent in my own question.

I guess a proper phrasing is "Given a theoretical object type called Foo, how do I fetch all instances of Foo"? Foo can be anything like Thread or Calendar or CalendarEvent (the latter two are the ones I'm interested in specifically).

[mdecimus]

That is not possible, the library does not offer a generic way to retrieve JMAP objects. Objects received from the JMAP server are deserialized using serde, so you'll have to implement the Calendar and CalendarEvent structures, make them de/serializable and finally write all the helper methods.

There are plans to support Calendar, Contacts and Tasks once the specifications are published.

Just to make sure that I'm understanding correctly, the lower level API is not public at all? Are there any plans to make that public, or is that a non-goal?

[mdecimus]

There is no lower API. As you may know, JMAP is basically JSON structures sent over HTTP. This library is simply a collection of methods that convert Rust structures into JSON using serde which are then transferred over HTTP using the reqwest crate.

Thanks for clarifying this. I see then that there's nothing for me to re-use here for a calendar implementation; I'd have to implement my own lower-level client first and then build the calendar implementation upon that.
