Welcome to the Rust community! This is a place to discuss about the Rust programming language.

The way I can think of to do this is to make a program called cargo-build-env which reads a file of your choosing with the features and executes cargo, then place that binary in your ~/.cargo/bin directory. Then you can run cargo build-env to build your program
The 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_bin
Then 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.
