Why is Rust slightly slower than C?

In what way can “STL” be considered a performance hit? It looks like you just threw out every C++-related word you know.

They probably meant, like everyone else who says that STL is a perf hit, "using STL containers is a perf hit"

You mean, passing along lies, knowingly or otherwise?

I have carefully benchmarked STL code against C-like loops and never got any measurable difference, even through multiple layers of abstraction.

Similarly, virtual function calls on modern CPUs are essentially free if the branch predictor can predict correctly, the usual case.

FUD from the '90s is way past its sell-by date.
