Struct Position 

pub struct Position {
    pub x: i32,
    pub y: i16,
    pub z: i32,
}

A Minecraft protocol block position packed into a 64-bit value.

The wire format stores x in the 26 most-significant bits, z in the middle 26 bits, and y in the 12 least-significant bits. Each component is a signed two’s-complement integer:

x: 26 bits | z: 26 bits | y: 12 bits

The value is packed as:

((x & 0x3FFFFFF) << 38) | ((z & 0x3FFFFFF) << 12) | (y & 0xFFF)

Examples

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

let position = Position {
    x: 18_357_644,
    y: 831,
    z: -20_882_616,
};

let mut encoded = Vec::new();
position.encode(&mut encoded)?;
assert_eq!(
    encoded,
    [0x46, 0x07, 0x63, 0x2c, 0x15, 0xb4, 0x83, 0x3f]
);

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

Fields

x: i32

The x coordinate, from -33,554,432 through 33,554,431.

y: i16

The y coordinate, from -2,048 through 2,047.

z: i32

The z coordinate, from -33,554,432 through 33,554,431.
