🦀 `de_env`

Deserialize environment variables through serde.

You may be looking for:

Example

Assuming we have a LOG and PORT environment variable:

```rust,no_run

struct Config { log: String, port: u16 }

let config: Config = deenv::fromenv().unwrap();

println!("{config:#?}"); ```

Boolean parsing is case-insensitive.

If the truthy-falsy feature is enabled (default):

Truthy values:
- true or its shorthand t
- yes or its shorthand y
- on
- 1
Falsy values:
- false or its shorthand f
- no or its shorthand n
- off
- 0

If the truthy-falsy feature is disabled, only true and false are considered valid booleans.

Only unit variants can be deserialized.

Assuming we have a LEVEL environment variable set to HIGH, MEDIUM or LOW:

```rust,no_run

enum Level { High, Medium, Low }

struct Pool { level: Level, }

let pool: Pool = deenv::fromenv().unwrap();

println!("{pool:#?}"); ```
