Enum Linkage 

pub enum Linkage {
    None,
    Internal,
    External,
}

Whether a name is shared with other translation units, and how.

Variants

None

The name is not shared. Block-scope objects without extern, parameters, and anything declared in a function’s body except a function or an extern object.

Internal

The name is shared within the translation unit and not outside it, which is what static at file scope means.

External

The name is shared with every translation unit that declares it.
