Struct SystemLabelId 

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

A type-erased system label identifier.

This wraps a Box<dyn SystemLabel> and provides the necessary trait implementations for use as a map key.

Example

use goud_engine::ecs::schedule::{SystemLabelId, SystemLabel, CoreSystemLabel};

let id = SystemLabelId::of(CoreSystemLabel::Input);
assert_eq!(id.name(), "Input");

Implementations

impl SystemLabelId

pub fn of<L: SystemLabel + Clone>(label: L) -> Self

Creates a new SystemLabelId from a label.

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

Returns the label’s human-readable name.

pub fn type_id(&self) -> TypeId

Returns the label’s type ID.

pub fn inner(&self) -> &dyn SystemLabel

Returns a reference to the inner label.

Trait Implementations

impl Clone for SystemLabelId

fn clone(&self) -> SystemLabelId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SystemLabelId

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

Formats the value using the given formatter.

impl Display for SystemLabelId

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

Formats the value using the given formatter.

impl Hash for SystemLabelId

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 SystemLabelId

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