Cargo env file?
Cargo env file?
Hello,
I have a project for which some machines have only a subset of features set. Currently, I write
cargo run --no-default-features --features "toto,titi" --bin my_bin
This is a bit cumbersome and I sometimes forget the --no-default-features --features part.
I was wondering if there is a local config file that I could put in the directory to instruct cargo to use this particular subset of features.
I guess this should be in the documentation, but I didn't find it.
The way I can think of to do this is to make a program called
cargo-build-envwhich reads a file of your choosing with the features and executes cargo, then place that binary in your~/.cargo/bindirectory. Then you can runcargo build-envto build your programThe program can be in any language as long as it's executable, including shell script
Yeah, a simple bash script should do. Such as:
#!/usr/bin/env bash BUILD_FEATURES=${BUILD_FEATURES:=default} cargo run --no-default-features --features "${BUILD_FEATURES}" --bin my_binThen just set a BUILD_FEATURES env var.
Not cargo, but I use justfiles in all my projects: https://github.com/casey/just Its great for aliasing project-specific commands like what you have.
You can setup a cargo configuration file, in it you put a manifest and define some profiles, and in them define what features you want compiled
This would look like it would be what I am looking for, but the documentation of the configuration file does not mention features.
