# Example

## Read a VarInt from a Read

```rust
use mc_varint::VarIntRead;
use std::io::Cursor;
fn main() {
    // firstly we create a Cursor
    let mut cur = Cursor::new(vec![0xff, 0xff, 0xff, 0xff, 0x07]);
    // secondly we read from it
    let value = cur.read_var_i32().unwrap();
    // the value is 2147483647
    assert_eq!(value, 2147483647);
}
```

## Write a VarInt to a Write

```rust
use mc_varint::{VarInt, VarIntWrite};
use std::io::Cursor;
fn main() {
    // firstly we create a Cursor and a VarInt
    let mut cur = Cursor::new(Vec::with_capacity(5));
    // secondly we write the VarInt to the Cursor
    cur.write_var_i32(2147483647).unwrap();
    // now the value is written to cur.
    assert_eq!(cur.into_inner(), vec![0xff, 0xff, 0xff, 0xff, 0x07]);
}
```
