A trait is the behavior half of a type with no shape at all. I measured a type of zero bytes carrying a trait, a million of them in a Vec with zero allocations, and a door that cannot be walked through while closed, all with nothing left in the binary. This is the kind of type I think most code does not use enough.

Exploring what dyn Trait is—and isn’t—in Rust, including type, lifetime, and generic distinctions that make it both powerful and complex.

This article explores the orphan rule in Rust and provides a practical workaround using the newtype pattern to implement traits you don't own for types you also don't own, ensuring code coherence and maintainability.

Learn how to work around Rust’s limitation of multi-trait objects by using a composite trait to combine multiple traits like `Read` and `Seek` into a single dynamic object.

Learn how to effectively convert a generic unsized parameter to a trait object in Rust, and understand the subtleties involved in handling `?Sized` and dynamic dispatch.
