Question Description

I'm trying to find an example of creating an aws_sdk_s3::Client with a custom cert.
I seem to be going around in circles trying the various TLS options with the various client/connector options.

with the following code:

extern crate dotenv;

use aws_sdk_s3::{Client, Error};
use aws_config::meta::region::RegionProviderChain;

use dotenv::dotenv;

#[tokio::main]
async fn main() -> Result<(), Error> {
    dotenv().ok();
    env_logger::init();
    let region_provider = RegionProviderChain::default_provider().or_else("us-east-1");
    let config = aws_config::from_env().region(region_provider).load().await;
    let client = Client::new(&config);

    let b = client.list_buckets().send().await?;

    println!("b: {:?}", b);

    Ok(())
}

I'm currently getting a Connection reset by peer error. I'm fairly certain this is because of my corporate network setup and the need to a custom cert chain. I've explored various option in order to use a custom crt file.
I've tried various combinations of rusttls and native-tls and composing hyper and hyper-tls as well as smithy but I can't work out the correct combination, let alone when or why I would choose one combination over another.

Any help appreciated.

Hello! In the process of trying to work up an example for you, I realized there are a couple of issues making this quite challenging. I filed #338 to track.

The next release will include a way to (relatively) easily provide your own connector for AWS config and generated clients. This isn't super ergonomic at the moment and we'll keep iterating on it

We now have a ca-cert example
