Enum Visibility 

pub enum Visibility {
    Default,
    Hidden,
    Protected,
}

How far outside a shared library a function’s name reaches.

Here for the reason Binding is here and not for any other: everything between the IR and the object file is handed machine functions, so a fact about the symbol that is not on one is a fact that is gone by the time anything can write it down. Nothing in this crate reads it.

The three the IR has, unnarrowed, because ELF says all three and the format is what decides how many there are rather than the machine.

Variants

Default

In the dynamic symbol table and interposable, which is what a name nothing marked gets.

Hidden

Not in the dynamic symbol table, so nothing outside the library can name it.

Protected

In the dynamic symbol table, and a call from inside the library binds to the definition inside it.
