Struct lief::pe::symbol::AuxiliaryWeakExternal

pub struct AuxiliaryWeakExternal<'a> { /* private fields */ }

“Weak externals” are a mechanism for object files that allows flexibility at link time. A module can contain an unresolved external symbol (sym1), but it can also include an auxiliary record that indicates that if sym1 is not present at link time, another external symbol (sym2) is used to resolve references instead.

If a definition of sym1 is linked, then an external reference to the symbol is resolved normally. If a definition of sym1 is not linked, then all references to the weak external for sym1 refer to sym2 instead. The external symbol, sym2, must always be linked; typically, it is defined in the module that contains the weak reference to sym1.
