Enum Difficulty 

#[repr(i32)]
pub enum Difficulty {
    Peaceful = 0,
    Easy = 1,
    Normal = 2,
    Hard = 3,
}

The difficulty level of the game.

Wire format

Encoded as a VarInt (0–3).

Variants

Peaceful = 0

Peaceful — no hostile mobs, health regenerates.

Easy = 1

Easy — hostile mobs deal less damage.

Normal = 2

Normal — default difficulty.

Hard = 3

Hard — hostile mobs deal more damage, hunger can kill.

Implementations

impl Difficulty

pub const fn id(self) -> i32

Returns the numeric ID of this variant.

pub const fn name(self) -> &'static str

Returns the lowercase name of this variant.

pub const fn by_id(id: i32) -> Option<Difficulty>

Looks up a variant by numeric ID.

pub fn by_name(name: &str) -> Option<Difficulty>

Looks up a variant by lowercase name.

pub fn read(buf: &mut Bytes) -> Result<Self, TypeError>

Reads this type from a wire buffer as a VarInt.

Errors

Returns TypeError if the buffer is truncated or the value is out of range.

pub fn write(&self, buf: &mut BytesMut)

Writes this type to a wire buffer as a VarInt.

Trait Implementations

impl Clone for Difficulty

fn clone(&self) -> Difficulty

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Difficulty

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Difficulty

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Difficulty

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Difficulty

fn eq(&self, other: &Difficulty) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
