Explore the concept of Zero-Cost Abstractions in Rust through this in-depth conference talk. Analyze generated code to determine the actual overhead of abstractions, using a running example to illustrate key points. Dive into intermediate representations, examine for loops, and compare Rust's approach to C. Gain insights into panic handling and understand the reasoning behind using two registers. Learn how to critically evaluate the true cost of seemingly cost-free abstractions in Rust programming.
