Read environment variables by lower, upper case or case-insensitive keys.
Unicode support for keys (comparing regardless of case) is enabled through the

[source,rust]
use unkasedenv::{uncased_var, lower_var, upper_var};
env::set_var("HeLlO", "world");
assert_eq!(uncased_var("Hello"), Ok("world".to_string()));
assert_eq!(lower_var("hello"), Ok("world".to_string()));
assert_eq!(upper_var("HELLO"), Ok("world".to_string()));
/* with `unicode` feature enabled */
env::set_var("Maße", "42");

:
Read environment variables by lower, upper case or case-insensitive keys
- This crate provides an interface similar to
std::env
but whose keys are - converted to lower or UPPER case, or presented in a way that can be compared
- regardless of case, either ASCII or Unicode (with feature
unicode
enabled, - using unicase).
- Only variants of
env::var
andenv::vars
are provided, sinceOsStr
s - are not necessarily human-readable character strings.
