Token does not implement serde::de::Deserialize about yup-oauth2 HOT 8 CLOSED

Actually I am having serious trouble compiling it myself. The only project that manages to compile it is google-apis-rs right now. Maybe the author of #19 can help with that too !

from yup-oauth2.

Maybe related to #23 .

from yup-oauth2.

Looking, I got the very same error. I'll try to reproduce.

from yup-oauth2.

@squidpickles Which version of serde_json are you using? yup-oauth2 is using 0.6.0, and if you use any other version than that, then there's an invisible type mismatch.

you could rewrite the compiler error as e.g.

error: the trait serde::de::Deserialize@serde_json-0.7.0 is not implemented for the type `yup_oauth2::common::Token` [E0277]

...although it implements serde::de::Deserialize@serde_json-0.6.0.

Try pinning your serde_json version to 0.6.0.

see also https://internals.rust-lang.org/t/dependency-hell-resolving-conflicting-version-requirements/1675. It's a similarly staggering error, but caused by different versions of one crate:

src/main.rs:513:9: 513:21 error: mismatched types:
 expected `rustc-serialize::json::Json`,
    found `rustc-serialize::json::Json`

from yup-oauth2.

@dermesser That's possibly what was happening.

I took a snapshot of all of the versions that were around the last time this compiled successfully.
The dependencies in my Cargo.toml look like this:

hyper = "0.7.2"
serde = "0.6.7"
serde_json = "0.6.0"
google-calendar3 = "0.1.10"
yup-oauth2 = "0.5.3"
time = "0.1.34"

(I notice it's not quite sticking to my desired versions. Is there a way to force maximum versions from the top level Cargo.toml?)

But, with those versions pinned, I get a new set of errors. The first:

My code does compile with this attached Cargo.lock. Maybe I can incrementally upgrade packages until I find the break...

from yup-oauth2.

See PR 24 (issue #23) for the form_urlencoded... error

from yup-oauth2.

This should now be fixed with release 0.6.0. I am planning to upgrade the URL crate soon as well, in case that matters.
