fn attribute<A: SysAttribute, T: FromStr<Err = E>, E>( &self, attr: A, ) -> Result<T, EitherErr2<Error, E>>

Get an attribute on the entity

fn attribute_str<A: AsRef<Path>>(&self, attr: A) -> IoResult<String>

Get an attribute by filename in the entity’s directory

fn exists<A: SysAttribute>(&self, attr: A) -> bool

This trait is not dyn compatible.

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