7c681fec66I ran the `bin/console spdx --fix` with different strategies for different files. For most of the core classes, since they've been drastically rebuilt, I've run it with the `git-blame` strategy, for for the `src/Validators`, in which the API changed completely but the logic remains the same, I use the `git-log` strategy.

# Unique
|
|
|
|
- `Unique()`
|
|
|
|
Validates whether the input array contains only unique values.
|
|
|
|
```php
|
|
v::unique()->assert([]);
|
|
// Validation passes successfully
|
|
|
|
v::unique()->assert([1, 2, 3]);
|
|
// Validation passes successfully
|
|
|
|
v::unique()->assert([1, 2, 2, 3]);
|
|
// → `[1, 2, 2, 3]` must not contain duplicates
|
|
|
|
v::unique()->assert([1, 2, 3, 1]);
|
|
// → `[1, 2, 3, 1]` must not contain duplicates
|
|
```
