Cross Team Collaboration: Rust Features and Ergonomics - 2021-11-22

Explore cross-team collaboration in Rust development through this 55-minute conference talk. Dive into nightly features, pinning techniques, and core modularization. Examine memory model considerations, const support implementations, and architecture-specific concerns. Learn about ergonomic improvements for operation tables and trait implementations. Discuss challenges in building the standard library, codegen quality, and padding solutions. Gain insights into the Rust specification, branded types for locking patterns, and function context restrictions.
