Struct VarInt 

pub struct VarInt(pub i32);

A variable-length two’s-complement signed 32-bit integer.

VarInts use one to five bytes on the wire. Each byte carries seven payload bits; the most-significant bit is set on every byte except the last.

Examples

use mcproto_types::{TypeCodec, basic::VarInt};

let mut encoded = Vec::new();
VarInt(25565).encode(&mut encoded)?;
assert_eq!(encoded, [0xdd, 0xc7, 0x01]);

let mut input = encoded.as_slice();
assert_eq!(VarInt::decode(&mut input)?, VarInt(25565));
assert!(input.is_empty());

Tuple Fields

0: i32

The integer value.
