Rust Is Not Yet A Better Language

• Questionable and at times dodgy Rust arithmetic
• Functional calls touch memory twice in Rust
• Rust is not faster than C++
• Unproven safety mechanism in Rust
• Painful rewrite of C library headers
• Compilation times are slow
• Rust is a pain, lacks transparency, and inconsistent to work with compiler where some things are documented rather than properly checked
• Integration with other languages is difficult
• Rust has a bigger assembly code footprint than C++
• Unsafe blocks are not checked
• Most of enterprise and technology products are built using C/C++/Java interface where a complete rewrite might be required for Rust
• Rust doesn't play nice with other languages
• Rust ecosystem tools are insufficient for prime time use
• Tedious and verbose
• No formal community specifications and release process
