Trait EntityRef 

pub trait EntityRef:

    // Required methods
    fn new(value: usize) -> Self;
    fn as_u32(&self) -> u32;
    fn as_usize(&self) -> usize;
}

An opaque reference to an entity.

Entity references are intended to be created only internally, and using manually constructed entity references (using EntityRef::new) may cause issues if you do not know what you are doing.

Required Methods

fn new(value: usize) -> Self

Creates an opaque reference to an entity.

Manually creating an entity reference may cause issues if you do not know what you are doing. Entity references are unchecked for performance reasons, and your program may panic if you create an invalid entity reference.

fn as_u32(&self) -> u32

Returns the raw ID of this entity reference.

Used internally to index an entity list.

fn as_usize(&self) -> usize

Returns the raw ID of this entity reference, as a Rust usize.

Used internally to index an entity list.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
