Performance

The mental model behind Rust performance work: what "zero-cost abstraction" actually promises, why allocation-awareness is a habit rather than a rule, and when to profile instead of guess.

Learn Rust performance basics with 10 examples. Understand release builds, zero-cost abstractions, and how to measure before optimizing code.

Learn how Rust's zero-cost abstractions like iterators and generics compile to efficient code, often matching hand-written loops.

Optimize Rust performance by avoiding unnecessary data cloning. Learn to use borrows, Cow, and ownership design for efficient data handling.

Reduce Rust binary size by stripping symbols, optimizing with opt-level="z", disabling features, and using panic = "abort" for smaller deployments.

Learn Rust performance best practices, including how to measure, optimize hot path code, and tune async services for production.
