Trait HasFields

pub trait HasFields {
    type Fields;

    // Required method
    fn fields() -> Self::Fields;
}

Users shouldn’t need to touch this directly; use the Fields derive and the HasFields trait generated for their own types.

Trait implemented for every type that derives Fields.

Obtain the root builder with Foo::fields() and then chain the generated methods (.bar().baz()…) to build dotted paths.

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.
