Trait SingleEntityQueryData 

pub unsafe trait SingleEntityQueryData: IterQueryData { }

A QueryData that only accesses data from the current entity, the one passed to QueryData::fetch.

This is used as a bound in EntityRef::get_components and related APIs, since they only have access to a single entity.

Safety

This QueryData must only access data from the current entity, and not any other entities.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
