(I have selfish reasons for opening the issue, I want to close https://github.com/rust-lang/docs.rs/issues/1102.)

The crate using dirs is rusoto_credential.

I'm willing to implement this and submit a PR if it would be accepted.

@brightly-salty There is already PR #1861, but no one looked into it. Looks like there are no active maintainers at the moment.

The state of this project makes me worried for the future of Rust in AWS.

@rimutaka Well, as I perceive, AWS hired tons of key people in Rust ecosystem in the last months, they even made a post about it.

Being truthful, I like Rust, really love it, tho the ecosystem sometimes is "not there yet" to solve the challenges that we face in the current company I work for.

I hope Rusoto get special attention by AWS planning in Rust wider adoption :)

1861 is merged now.
