Struct Entity 

pub struct Entity(/* private fields */);

A handle to an entity in the ECS world.

Upper 32 bits = generation, lower 32 bits = index.

Implementations

impl Entity

pub fn new(index: u32, generation: u32) -> Self

Create an entity from an index and generation.

pub fn index(self) -> u32

Index portion (lower 32 bits).

pub fn generation(self) -> u32

Generation portion (upper 32 bits).

pub fn id(self) -> u64

Raw u64 id.

pub fn from_id(id: u64) -> Self

Reconstruct an entity from a raw u64 id.

Trait Implementations

impl Clone for Entity

fn clone(&self) -> Entity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Entity

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

Formats the value using the given formatter.

impl Display for Entity

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

Formats the value using the given formatter.

impl Hash for Entity

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 Entity

fn eq(&self, other: &Entity) -> 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.
