Trait Constr 

pub trait Constr {
    const STR: &'static str;
}

Constant string “type”.

To get around the lack of constant string generics, we use types that implement this trait to provide generic strings instead.

To easily construct zero-sized types which implement this trait, see constr!.

Required Associated Constants

const STR: &'static str

String 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.

Implementors
