Fine tuning settings

rustcbuildx@version: $RUSTC_WRAPPER tool to sandbox cargo builds and execute jobs remotely
    https://github.com/fenollp/rustcbuildx

Usage:
  rustcbuildx env             Show used values
  rustcbuildx pull            Pulls images (respects $DOCKER_HOST)
  rustcbuildx -h | --help
  rustcbuildx -V | --version

Remote execution

Say you have a bigger machine in your ~/.ssh/config called extra_oomph:

export DOCKER_HOST=ssh://extra_oomph
# Then
export RUSTC_WRAPPER=rustcbuildx
cargo test ...

• Build cache is saved remotely
• Build artifacts are saved locally
• Tests building happens on remote machine
• Tests execution happens on local machine

Installation

# Installs to ~/.cargo/bin
cargo install --locked --force --git https://github.com/fenollp/rustcbuildx.git

# Make sure it's in your $PATH
which rustcbuildx
