A lightweight Curl-wrapper for using (mostly) HTTP from Rust.
While there are a couple of Rust HTTP libraries like rust-http and its successor teepee. But the first one is considered deprecated and the second one is not pretty usable yet. Plus SSL support comes only with OpenSSL.
Curl, in other hand, has pretty good history + allows to use a lot of different SSL backends, for example, it works with Apple security frameworks on Mac/iOS. It also can be used to support other protocols although they're not in plans in near future.
I hope situation in Rust-land will change soon and it will be possible to drop this one in favor of Rust-only stack.
