About

Like dotenv but with .cargo/config.toml files

$ env |grep ^CARGO_ENV_RUN_TEST
$ cat .cargo/config.toml
[env]
CARGO_ENV_RUN_TEST = "IT WORKS"
$ cargo env-run env |grep ^CARGO_ENV_RUN_TEST
CARGO_ENV_RUN_TEST=IT WORKS

This crate/utility does not intend to replace dotenv or similar utilites, and was originally designed to overcome Helix Editor's inability to recognize a compile-time environment variable being set in a .cargo/config.toml file instead of the current environment. Using this utility, the fix for this scenario is to prefix the hx src/main.rs command with cargo env-run which loads environment variables from .cargo/config.toml files and then runs the given command.
