Trait Id

pub trait Id:
    Copy
    + Eq
    + Hash
    + Ord
    + Send
    + Sync
    + Sized
    + 'static {
    // Required methods
    fn from_u32(value: u32) -> Self;
    fn id(&self) -> u32;
}

The ids component storages are indexed with. This is mostly just a newtype wrapper with a u32 in it.

Examples

use specs_static::Id;

#[derive(Clone, Copy, Debug, Eq, Hash, Ord, PartialEq, PartialOrd)]
pub struct MyAmazingId(pub u32);

impl Id for MyAmazingId {
    fn from_u32(value: u32) -> Self {
        MyAmazingId(value)
    }

    fn id(&self) -> u32 {
        self.0
    }
}

Required Methods

fn from_u32(value: u32) -> Self

Creates an idea from a u32.

fn id(&self) -> u32

Returns the id integer value.

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.
