Enum Binding 

#[non_exhaustive]
pub enum Binding {
    Local,
    Global,
    Weak,
}

Who can see a symbol: this object only, or every object in the link.

Examples

use object_lang::{Binding, Symbol};

assert_eq!(Symbol::undefined("f").binding, Binding::Global);
assert_eq!(Symbol::file("main.c").binding, Binding::Local);

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Local

Visible only inside this object.

Global

Visible to every object in the link; two global definitions of one name clash.

Weak

Like global, but yields to a global definition of the same name, and an undefined weak reference resolves to zero instead of failing the link.
