Create virtual, activate-able environments for Rust, similar to virtualenv
for Python.
A virtual environment is a self-contained installation of Rust, Cargo, etc., which is completely isolated from any user-level installations you may have.
For example:
# Create a new rustenv
$ rustenv renv
# Run a command in it
$ renv/bin/rustc --version
rustc 1.26.1 (827013a31 2018-05-25)
$ renv/bin/cargo --version
cargo 1.26.0 (0e7c5a931 2018-04-06)
# Activate it to avoid having to prefix your commands
$ . renv/bin/activate
(renv) $ rustc --version
rustc 1.26.1 (827013a31 2018-05-25)
# Install hello-cli: https://crates.io/crates/hello-cli
(renv) $ cargo install hello-cli
(renv) $ hello
Hello World!
# Deactivate it to restore your PATH and PS1
(renv) $ deactivate_rustenv
$ rustc --version
command not found: rustcrustenv is available via PyPI and can be
installed using pip:
$ pip install rustenv- Everything in the example above.
- Provide some additional options when creating the rustenv:
- Allow specifying rustc / cargo version
- Allow disabling PS1 modification, similar to virtualenv
- ...and more? (file an issue! :))
