Rust
- Overview
- A memory-safe interpretation of C++
- Unsafe pointers are not allowed (e.g. x = 0x1234)
- Type Inference
- Boxes (memory shared between threads but owned by the creating thread)
- Traits (interfaces which allow function bodies but no fields)
- Two runtimes: native and green
- In Native, each task is a thread
- In Green, you specify a threadpool and each task is a coroutine
- History
- Personal project for a mozilla employee
- Still in alpha mode (using stable releases is discouraged)
- Very basic support for thrift for connecting to other languages
- Pros
- Uber smart compiler
- Great standard library
- Auto serialization to/from json/base64/hex
- Army of useful collections (BTree, Trie, LRU, Arena, etc.)
- GraphViz for creating dot files from rust collections
- Many more
- Cons
- Slower than C++ (But not much)
- Too early to use reliably
- Third party libraries are lacking / immature
