    None,
    Internal,
    External,
}

The linkage of an identifier determines the scope that it can be referenced from.

External

Implementations

impl AstLinkage

pub fn has_linkage(&self) -> bool

Does the identifier have linkage?

In other words, is the linkage Internal or External (but not None). An identifier with linkage must be defined at file scope, but an identifier can be declared with external linkage at any scope.

Trait Implementations

impl Clone for AstLinkage

fn clone(&self) -> AstLinkage

Returns a duplicate of the value.

impl PartialEq for AstLinkage

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
