Cargo behind SOCKS proxy

[kornelski]

I have to use a SOCKS proxy (the kind created by ssh -D). The documentation doesn't say whether/how SOCKS is supported:

proxy = "..." # HTTP proxy to use for HTTP requests (defaults to none)

I've tried changing config, as mentioned in #636, but Cargo seems to assume the proxy is a HTTP proxy. I've tried:

[http]
proxy = "socks://localhost:9050"
[https]
proxy = "socks://localhost:9050"

but that's not enough:

cargo run
Updating registry https://github.com/rust-lang/crates.io-index
warning: spurious network error (2 tries remaining): [12/-2] [6] Couldn't resolve host name (Could not resolve host: github.com)
warning: spurious network error (1 tries remaining): [12/-2] [6] Couldn't resolve host name (Could not resolve host: github.com)
error: failed to load source for a dependency on vpsearch

Caused by:
Unable to update registry https://github.com/rust-lang/crates.io-index

Caused by:

Are SOCKS proxies supported?

I believe the syntax for libcurl is the socks5 or socks5h protocol (e.g. socks5://localhost:9050). Does that work?

socks5h worked, thank you!
