Rust

Looking for the best resources on understanding the costs of dynamic dispatch in Rust. 

We’re refactoring some things in Lasso to support Jolt — anecdotally the cost seems tiny, but hoping to understand long term implications

Did my time in big tech, since recovered.

you won't notice any performance difference unless the call is in some very hot path called many millions of times

Assuming you need dyns, the best way to estimate app impact is prototyping. I would guess its small, but i also don't know how perf sensitive your codepaths are.

This is a great resource on the topic I watched a while back: https://youtu.be/xcygqF5LVmM

From a code structure/maintainability pov, what's the biggest win you'll get from refactoring to dynamic dispatch? 

Perf cost is small (but non zero) and improves compiled binary size.
