Version incompatibility when upgrading to 1.0.3

[simon-an]

Hey there,

if someone is facing an issue because of indexmap was upgraded as part of a patch version you can just pin this crate like this:

openapiv3 = "=1.0.2" # pinned because paperclip does not support indexmap v2.0.0 which cames with 1.0.3

Thanks for not doing proper semver by expecting everyone just pins all depencies by default. 👎

1.0.3 accepts a range of indexmap versions. You should not need to upgrade to 2.0.0. Happy to help you work through whatever issues you've encountered when upgrading.

I just seen this on another issue. The problem is that paperclip uses version 1 so it creates type incompatibility:

   = note: `IndexMap<_, _>` and `IndexMap<String, Value>` have similar names, but are actually distinct types
note: `IndexMap<_, _>` is defined in crate `indexmap`
  --> /Users/tiagocastro/.cargo/registry/src/index.crates.io-6f17d22bba15001f/indexmap-1.9.3/src/map.rs:71:1
   |
71 | pub struct IndexMap<K, V, S = RandomState> {
   | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
note: `IndexMap<String, Value>` is defined in crate `indexmap`
  --> /Users/tiagocastro/.cargo/registry/src/index.crates.io-6f17d22bba15001f/indexmap-2.0.0/src/map.rs:81:1

From what I can tell by having this ">=1.6.1, <3.0.0" actually it picks 2.0 because the latest dep serde_yaml has ^2.0 so this can never work with paperclip. I made it work by doing this hack:

cargo update -p [email protected] --precise "1.9.3"
cargo update -p serde_yaml --precise "0.9.21"

So how to fix this? We can upgrade paperclip to use index map 2 though I feel this may still be brittle if openapiv3 changes again to allow for a future index map v3 for example..

EDIT: paperclip-rs/paperclip#508

I just ran into this problem again. It seems to be a problem whenever there is a dependency wanting ^1.0 and one wanting ^2.0, making cargo pick "whatever of the two it feels like" for openapiv3. It is probably best to always pick one of the two version for public dependencies.
