Struct cradle::Env

pub struct Env<Key, Value>(pub Key, pub Value)
 where
    Key: AsRef<OsStr>,
    Value: AsRef<OsStr>;

Adds an environment variable to the environment of the child process.

use cradle::*;

let StdoutUntrimmed(output) = cmd!("env", Env("FOO", "bar"));
assert!(output.contains("FOO=bar\n"));

Child processes inherit the environment of the parent process. Env only adds environment variables to that inherited environment. If the environment variable is also set in the parent process, it is overwritten by Env.
