Rust is defined as a safe, low-level, system programming language directly competing with C++.

How much does it pay for safety in terms of performance ? Can we expect similar performance on idiomatic code ?

In this talk we

• identify performance weak spots (and strong points) of Rust
• check how bad (or good) they are in practice
• propose countermeasures / performance best practices

The talk was delivered at C++Russia 2026 and also published on
