Overview

This library has many helper functions to access/modify/check environment variables.

Usage

Simply include the library and invoke the various utility functions, for example:

Get/Set/Remove environment variables

```rust extern crate envmnt;

fn main() { if !envmnt::exists("MYENVVAR") { envmnt::set("MYENVVAR", "SOME VALUE"); }

let mut value = envmnt::get_or("MY_ENV_VAR", "DEFAULT_VALUE");
println!("Env Value: {}", &value);

value = envmnt::get_or_panic("MY_ENV_VAR");

let pre_value = envmnt::get_set("MY_ENV_VAR", "SOME NEW VALUE");

let value = envmnt::get_or("MY_ENV_VAR", "DEFAULT_VALUE");
println!("New Env Value: {}", &value);
println!("Previous Env Value: {:?}", &pre_value);

let all_vars = envmnt::vars(); // returned as Vec<(String, String)>

for (key, value) in all_vars {
    println!("{}: {}", key, value);
}

} ```

Get/Set boolean environment variables and other comparisons

```rust extern crate envmnt;

fn main() { envmnt::setbool("FLAGVAR", true); let flagvalue = envmnt::isor("FLAGVAR", false); println!("Bool Flag: {}", &flagvalue);

let pre_value = envmnt::get_set("MY_ENV_VAR", "SOME NEW VALUE");

envmnt::set("MY_ENV_VAR", "SOME VALUE");
let same = envmnt::is_equal("MY_ENV_VAR", "SOME VALUE");
println!("Value Is Same: {}", &same);

} ```

Bulk Operations

```rust extern crate envmnt;

fn main() { let mut found = envmnt::isanyexists(&vec![ "ENVVAR1", "ENVVAR2", ]);

println!("Any Found: {}", &found);

found = envmnt::is_all_exists(&vec![
    "ENV_VAR1",
    "ENV_VAR2",
]);

println!("All Found: {}", &found);

} ```
