Struct VarLong 

pub struct VarLong(pub i64);

A variable-length two’s-complement signed 64-bit integer.

VarLongs use one to ten 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::VarLong};

let mut encoded = Vec::new();
VarLong(9_223_372_036_854_775_000).encode(&mut encoded)?;

let mut input = encoded.as_slice();
assert_eq!(
    VarLong::decode(&mut input)?,
    VarLong(9_223_372_036_854_775_000),
);
assert!(input.is_empty());

Tuple Fields
