# Хз зачем, просто по приколу написал

Это, что-то вроде представления базы данных об учебных заведениях для начального и средного образований.

# School Rust Library

This Rust library provides structures to manage school-related data, including students, classes, and schools.

## Usage

To use this library, add the following to your `Cargo.toml`:

```toml
[dependencies]
school_library = "1.0.0"
```

Then, in your Rust code:

```rust
use school_library::{School, Class, Student, Grades};
```

### Grades

Represents grades for different subjects.

```rust
let grades = Grades::new(90, 85, 88, 92, 78, 87, 91, 95, 89);
let random_grades = Grades::gen();
```

### Student

Represents a student with an ID, name, age, and grades.

```rust
let student = Student::new(1, String::from("John Doe"), 16, &grades);
```

### Class

Represents a class with a name and a list of students.

```rust
let class = Class::new(String::from("Math Class"), vec![student1, student2]);
class.add_student(&new_student);
```

### School

Represents a school with a name, a number of students, and a list of classes.

```rust
let mut school = School::new(String::from("High School"), vec![class1, class2]);
school.add_class(&new_class);
let average_grades = school.average_grades();
let best_class = school.get_best();
```
