Reqwest: would you please replace hyper-tls with hyper-rustls

[29e7e280-0d1c-4bba-98fe-f7cd3ca7500a]

https://github.com/ctz/hyper-rustls

The rustls is the pure rust tls solution. no more need openssl.
I got trouble in compile reqwest with openssl static linked.

I can not solve the problem .

[blackghost1987]

I had the same problem, that's one of the reasons I'm still using Hyper instead of Reqwest. Although Rustls is still not stable according to their site, so a more conservative approach would be to make it an opt-in feature.

[seanmonstar]

A problem that shows up if this is a Cargo feature is that some libraries might elect to use the default native-tls feature, and others to use a rustls feature.

---

To the question in the title: I would not move reqwest from using native-tls to rustls by default at this point in time. native-tls leads to smaller binaries on Windows and OSX. It also uses more mature libraries. rustls, while I am excited for its existence and am rooting for it, is not at a point where I could responsibly say it should be the default used in a fundamental crate. It doesn't support all TLS versions, and it hasn't been audited.

In the future: hopefully!

The current openssl rust can not build .

Rust lang mother fucker.. stupid.

@netroby looks like the linker can't find symbols from the openssl library.

• Do you have the headers installed? As rust-openssl points out, the headers are sometimes not included in the main openssl package, but a separate package like libssl-dev or openssl-devel.
• If you do have them, maybe they aren't installed in the usual place? You can tell rust-openssl where the library is with some environment variables.

Couldn't this issue be solved by allowing clients to be set up with custom hyper::client::Connects? They you would be able to pass in a hyper_rustls::HttpsConnector.
