The naive reference is the pointer in c programming language.In c language, we use & and * operator to reference and dereference one data structure, such as bellow:
data_t *p = &data; //!< reference `data` *p; //!< dereference `data`
Primitive reference type
The modern programming language not recommend pointer but independent reference type.In c++ language, we use & operator to reference data structure and automatic dereference the reference by compiler, such as bellow:
data_t &r = data; //!< reference `data` r; //!< automatic dereference `data`
The difference of Pointer, Reference
The Ownership and Borrowing
The Ownership and Borrowing is the concepts in RUST programming language.But they are related to reference for that reference is one implementation of Borrowing.
The main difference of Ownership and Borrowing is the
Drop trait, Owner implement it but Borrower not.There are some same concepts in other languages, such as Smart Pointer(One implementations of Ownership) and reference(One implementation of Borrowing) in c++, through they distinguish Ownership by destructor.
There are some typical implementations of Ownership and Borrowing in RUST as bellow:
|Box, Rc and String etc.||reference, slice and Iter etc.|
