Trait WorldFilter 

pub trait WorldFilter: Any {
    // Required methods
    fn filter(components_ids: &'static [TypeId]) -> bool;
    fn filter_by_meta(meta: &mut BundleMeta) -> bool;
}

用来过滤Bundle

作为WorldFetch的附属使用

Required Methods

fn filter(components_ids: &'static [TypeId]) -> bool

传入Bundle的components_ids

• 返回true表示通过
• 返回false表示没

fn filter_by_meta(meta: &mut BundleMeta) -> bool

加速版本,会从缓存读取,否则重新计算

主要是为了让嵌套的WorldFilter可以更快

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.
