# ward
This crate exports two macros, which are intended to replicate the functionality of Swift's guard
expression with `Option<T>` usage. They both do similar things, but the `ward!` macro technically
has more use cases than the `guard!` macro, because it returns a value instead of creating a
variable.
## Examples
```rust
let sut = Some("test");
// This creates the variable res, which from an Option<T> will return a T if it is Some(T), and will
// otherwise return early from the function.
guard!(let res = sut);
assert_eq!("test", res);
```
The `ward!` macro, by comparison, just returns the value, without forcing you to make a variable
from it (although we still do in this example):
```rust
let sut = Some("test");
let res = ward!(sut);
assert_eq!("test", res);
```
Both macros also support an `else` branch, which will run before the method returns early:
```rust
let sut = None;
guard!(let _res = sut, else {
println!("This will be called!");
});
unreachable!();
```
