- Evalute function which will modify the read value before it is loaded into the environment
Example
extern crate envmnt; extern crate indexmap; 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 = |value: String| { let mut buffer = String::from("VALUE-"); buffer.push_str(&value); buffer }; envmnt::evaluate_and_set_all(&env, eval_env); let mut value = envmnt::get_or_panic("MY_ENV_VAR"); assert_eq!(value, "VALUE-MY VALUE"); value = envmnt::get_or_panic("MY_ENV_VAR2"); assert_eq!(value, "VALUE-MY VALUE2"); }
