Enum Linkage 

pub enum Linkage {
    External,
    Appending,
    Internal,
    WeakAny,
    WeakOdr,
    LinkOnceAny,
    LinkOnceOdr,
    ExternWeak,
    Common,
    Private,
    AvailableExternally,
}

How a global value links (LLVM’s LinkageTypes, decoded from the bitcode’s linkage codes).

Variants

External

Visible to other modules (codes 0, 5, 6 and 15).

Appending

Appended to the same-named array of other modules (2).

Internal

Local to the module (3).

WeakAny

Weak, kept even where unreferenced (16).

WeakOdr

Weak, every definition equivalent (17).

LinkOnceAny

Merged with other definitions, dropped where unreferenced (18).

LinkOnceOdr

As LinkOnceAny, every definition equivalent (19).

ExternWeak

A weak reference to an external symbol (7).

Common

A tentative definition (8).

Private

Local to the module and left out of its symbol table (9, 13 and 14).

AvailableExternally

Defined elsewhere, given here for optimisation (12).

Trait Implementations

impl Clone for Linkage

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Linkage

impl Debug for Linkage

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Linkage

fn default() -> Self

Returns the “default value” for a type.

impl Eq for Linkage

impl PartialEq for Linkage

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
