# Okey - Everything is Result::Ok...

Ideally this crate should ~~not be used~~ used with the [macro_rules_attribute](https://crates.io/crates/macro_rules_attribute)
crate from [Daniel Henry-Mantilla](https://github.com/danielhenrymantilla). So make sure to install that too...

```shell
cargo add macro_rules_attribute
```

## Usage

```rust
#[macro_use]
extern crate macro_rules_attribute;

use okey::okey;

#[apply(okey)]
fn my_name() -> Result<&'static str> {
    return "David";
}
```

In the example above `my_name` will automatically return a `Result::Ok` variant with `"David"` as it's inner value.

Note that this won't work with "implicit returns", you need to explicitly put the `return` keyword for this to work.

### Returning an error

```rust
#[macro_use]
extern crate macro_rules_attribute;

use okey::okey;

#[apply(okey)]
fn my_name() -> Result<&'static str> {
    return Err(some_error());
}
```
