Function envmnt::evaluate_and_set_all

pub fn evaluate_and_set_all<F>(env: &IndexMap<String, String>, evaluate: F) where
    F: Fn(String, String) -> Option<(String, String)>, 

Sets all the provided env key/value pairs.

Arguments

• env - The environment variables to set
• evaluate - Evalute function which will modify the key/value before it is loaded into the environment

Example

use indexmap::IndexMap;

fn main() {
    let mut env: IndexMap<String, String> = IndexMap::new();
    env.insert("MY_ENV_VAR".to_string(), "MY VALUE".to_string());
    env.insert("MY_ENV_VAR2".to_string(), "MY VALUE2".to_string());

    let eval_env = |key: String, value: String| {
        let mut updated_key = String::from("KEY-");
        updated_key.push_str(&key);
        let mut updated_value = String::from("VALUE-");
        updated_value.push_str(&value);
        Some((updated_key, updated_value))
    };

    envmnt::evaluate_and_set_all(&env, eval_env);

    let mut value = envmnt::get_or_panic("KEY-MY_ENV_VAR");
    assert_eq!(value, "VALUE-MY VALUE");
    value = envmnt::get_or_panic("KEY-MY_ENV_VAR2");
    assert_eq!(value, "VALUE-MY VALUE2");
}
