Struct Angle 

pub struct Angle(pub u8);

A rotation angle encoded in steps of 1/256 of a full turn.

The wire value is a single byte. Because 256 steps represent one full turn, the value wraps around and its signedness does not matter.

Examples

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

let angle = Angle(64);

let mut encoded = Vec::new();
angle.encode(&mut encoded)?;
assert_eq!(encoded, [64]);

let mut input = encoded.as_slice();
assert_eq!(Angle::decode(&mut input)?, angle);

assert_eq!(angle.to_degrees(), 90.0);
assert!((angle.to_radians() - std::f64::consts::FRAC_PI_2).abs() < 1e-12);

Tuple Fields

0: u8

The raw angle step count, from 0 through 255.

Implementations

impl Angle

pub fn to_degrees(&self) -> f64

Returns the angle in degrees.

A full turn of 256 steps is equivalent to 360 degrees.

pub fn to_radians(&self) -> f64

Returns the angle in radians.

A full turn of 256 steps is equivalent to 2π radians.
