## Features

The crate is heavily inspired by [AssertJ](https://assertj.github.io/doc/)

- simple and readable syntax
- assertions based on the type of the asserted value
- assertion values use type conversion traits to make assertions readable

## Examples

All asserted are stared by calling `assert_that` on a value.  
After that various assertions based on the type of the asserted value can be made.

```rust
use smoothy::assert_that;

assert_that(42).equals(42);
```

```rust
use smoothy::assert_that;

assert_that(1u8).try_into_equals(1i8);
```

```rust
use smoothy::assert_that;

assert_that(String::from("Hello")).equals("Hello");
```

```rust
use smoothy::assert_that;

let result: Result<u8, String> = Ok(42);
assert_that(result)
    .is_ok()
    .and_value_equals(42);
```

```rust
use smoothy::assert_that;

let result: Result<(), String> = Err(String::from("ups!"));
assert_that(result)
    .is_err()
    .and_error_to_string_equals("ups!");
```

## TODO:

- option support
- vec support (length, contains)
- string support (length, contains, starts_with, ends_with)
