Rust: Store Data on the Heap with Box

Video Description

#rust #smart #box ! At 1:08, I said "Defer Trait", but I actually mean "Deref Trait" Box is a straightforward example of one Smart Pointer in Rust. Box allows you to store data on the heap instead of the stack. Instead of passing around your data, and copying it’s total memory on the stack, you can use a Box to store the data and avoid the memory copies on the stack and defer to pointer copies on the stack. This is the single responsibility of the Box. Box is a smart pointer because it implements the `Defer trait` which allows the `T` to be treated like references. If you are unfamiliar with the concept of stack vs. heap, please refer to The Rust Programming Book chapter 4. 0:00 intro 2:05 Using Box to Store Data on the Heap 3:11 Enabling Recursive Types with Boxes 5:55 Computing the Size of a Non-Recursive Type 8:10 Using Box to Get a Recursive Type with a Known Size Links Learn more about traits https://doc.rust-lang.org/book/ch17-02-trait-objects.html Box documentation https://doc.rust-lang.org/std/boxed/index.html
