Appendix E. Rust compared to other languages

• Rust has structs and impl.

  • C++, Java, Python, JavaScript have classes.
  • C doesn’t have classes, but it has structs.
    • However, no function methods can be placed.

• Rust has generics

  • C++ and Java have it too.
  • C and Python do not.
    • Python doesn’t need it.
  • Go is adding them.

• Rust has traits

  • Java and Go have interfaces.

Features unique to Rust

• The fact that by default variables are not mutable. In other languages you have to specify “const” to get the opposite effect.

• Move by default instead of Copy.

• Ownership and Borrowing.

• No Garbage Collector and no manual memory management (At the same time)

  • C/C++ have no GC, but manual memory allocation.
  • Almost every other language has a GC.
