A fork of dotenv-rs that adds support for the popular dotenv-flow loading strategy.
The dotenv-flow strategy works as follows:
Each step will only load variables that are not already present in the environment, so for example variables in the .env.{DOTENV_ENV}.local file will have the highest priority, followed .env.local and so on.
cargo add dotenv-flow
To use this package, add the following line to your main function to load the environment variables from available .env.*
files:
fn main() {
dotenv_flow::dotenv_flow().ok();
}
To test this project, make sure you pass --test-threads=1
to cargo test
, e.g.
cargo test -- --test-threads=1
This is necessary because cargo test
runs tests in multiple threads by default, but environment variables are process-globals, therefore we need to limit concurrency to avoid race conditions.
