Discover how the Rust compiler optimizes dynamically dispatched tail calls and manages memory when using trait objects in this in-depth tutorial. Gain a deeper understanding of how vtables and the Rust memory model work together to improve the performance of your code.

This article will investigate how Rust handles dynamic dispatch using trait objects and vtables. We will also explore how the Rust compiler can sometimes optimize tail calls in the context of dynamic dispatch. Finally, we will examine how the vtable facilitates freeing memory when using trait objects wrapped in a Box.
