An in-depth visualization explaining how Rust's dynamic dispatch works under the hood through vtables (virtual method tables). The article breaks down the memory layout of dyn Trait objects and demonstrates how trait method resolution happens at runtime.
Background
Rust's trait system is a core language feature, and understanding dyn Trait and vtable dispatch is essential for writing efficient Rust code. Many developers seek deeper understanding of the memory representation behind dynamic dispatch.
