Last year Tor began to ship with Rust
components. In
theory the C code in the daemon is going to be slowly replaced by Rust.
A major component of the Rust ecosystem is the command-line tool cargo which
helps with dependency resolution, tool installation, and build processes. Out
of the box cargo does not appear to work very well with Tor. Fortunately this
is easy to fix with a simple configuration change.
As of version 1.34.0, cargo supports directly utilizing the Tor SOCKS proxy:
[http]
proxy = "socks5h://localhost:9050"
With this addition to ~/.cargo/config, cargo should route traffic through Tor.
