🐛 Bug description

There seems to be a dependency version issue with dynomite and rusoto_core. Using code from the examples, pared down, does not compile because of mismatched types.

🤔 Expected Behavior

I expected this code to compile.

👟 Steps to reproduce

Create the Cargo.toml and main.rs that I have provided and run cargo check

🌍 Your environment

Ubuntu 20.04

dynomite version: 0.10

rustc version: rustc 1.49.0 (e1884a8e3 2020-12-29) cargo 1.49.0 (d00d64df9 2020-12-05)

@jeremymcjunkin I just ran into this and tracked down the cause with cargo tree. Dynomite's master branch is pretty far ahead of 0.10, so you're going to want to crib from the examples under the 0.10 tag, not master. In particular, 0.10 is still using the 0.45 release of Rusoto, although there are some other changes as well.

Thanks @terrence2 ,

I was able to get it to compile with Cargo.toml

[dependencies]
dynomite = { version = "0.10.0", default_features = true }
rusoto_core_default = { package = "rusoto_core", version = "0.45", optional = true }

[features]
default = ["rusoto_core_default"]

src/main.rs

use rusoto_core_default::Region;

use dynomite::{
  dynamodb::{
      DynamoDbClient
  },
};

fn main() {
  let _client = DynamoDbClient::new(Region::default());
}

It's unclear to me why I needed to add

rusoto_core_default = { package = "rusoto_core", version = "0.45", optional = true }

[features]
default = ["rusoto_core_default"]

To pull in rusoto_core_default. Shouldn't

dynomite = { version = "0.10.0", default_features = true }

Pull rusoto_core_default because it's listed in the default features for dynomite? https://github.com/softprops/dynomite/blob/v0.10.0/dynomite/Cargo.toml#L43

[features]
default = ["uuid", "chrono", "derive", "rusoto_core_default", "rusoto_dynamodb_default"]
rustls = ["uuid", "chrono", "derive", "rusoto_core_rustls", "rusoto_dynamodb_rustls"]
derive = ["dynomite-derive"]

I had the same issue and switched to the master branch in Cargo.toml: dynomite = { git = "https://github.com/softprops/dynomite.git" }
