Cargo Remote

Use with caution, I didn't test this software well and it is a really hacky (at least for now). If you want to test it please create a VM or at least a separate user on your build host

Why I built it

One big annoyance when working on rust projects on my notebook are the compile times. Since I'm using rust nightly for some of my projects I have to recompile rather often. Currently there seem to be no good remote-build integrations for rust, so I decided to build one my own.

Planned capabilities

This first version is very simple (could have been a bash script), but I intend to enhance it to a point where it detects compatibility between local and remote versions, allows (nearly) all cargo commands and maybe even load distribution over multiple machines.

Usage

For now only cargo remote [FLAGS] [OPTIONS] <command> works: it copies the current project to a temporary directory (~/remote-builds/<project_name>) on the remote server, calls cargo <command> remotely and optionally (-c) copies back the resulting target folder. This assumes that server and client are running the same rust version and have the same processor architecture. On the client ssh and rsync need to be installed.

Configuration

You can place a file called .cargo-remote.toml in the same directory as your Cargo.toml. There you can define a default remote build host and user. It can be overridden by the -r flag.

Example .cargo-remote.toml:

remote = "builds@myserver"
