Struct ComponentKey 

pub struct ComponentKey { /* private fields */ }

Used as a key for Component storage. Component instances receive these in their constructor methods, and should retain them as a tool to update their state.

Implementations

impl ComponentKey

pub fn placeholder() -> ComponentKey

A placeholder value, used purely for ensuring the diffing algorithm remains readable by reducing some unwrapping hell.

Trait Implementations

impl Clone for ComponentKey

fn clone(&self) -> ComponentKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ComponentKey

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

Formats the value using the given formatter.

impl Hash for ComponentKey

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 ComponentKey

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