adotenv-process

Explicit process-environment mutation for adotenv loaded environments.

use adotenv::load::load_cascade;
use adotenv_process::apply;

let loaded = load_cascade("/srv/my-app", "production")?;
// The caller must guarantee no concurrent process-environment access.
unsafe { apply(&loaded)? };

apply validates every key and value before the first mutation. It sets only keys from the loaded environment and cannot roll changes back. The process environment is global, so the caller owns the concurrency guarantee.

Prefer iterating or collecting LoadedEnvironment::values() when mutation is not required.

This is the only workspace crate with an unsafe API. The core adotenv crate forbids unsafe code. The crate supports Rust 1.81.
