Zero-Cost Abstractions
A core design principle of the Rust programming language, stating that high-level abstractions incur no additional runtime overhead after compilation. Code written using high-level syntax performs equivalently to manually written low-level code.

Zero-cost abstraction is a core design philosophy of Rust, meaning that high-level syntactic sugar such as iterators, generics, and trait objects is optimized by the compiler into machine code equivalent to hand-written assembly without introducing runtime overhead.
Rust's vtable design ensures that ordinary structs do not increase in size simply because they might be used as trait objects, consistent with the zero-cost abstraction philosophy.
Zero-Cost Abstraction means that high-level abstractions do not incur additional runtime overhead after compilation, and the generated machine code is equivalent to hand-written low-level code.
