Trait Implementations

impl Clone for Extern

fn clone(&self) -> Extern

Returns a copy of the value.

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

impl Debug for Extern

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

Formats the value using the given formatter.

impl<'a> Exportable<'a> for Extern

fn to_export(&self) -> Export
