Rust Lang Team Design Meeting: &T and Dereferenceable Optimizations - 2020.02.10

Explore the intricacies of Rust's Lang Team Design Meeting from February 10, 2020, focusing on &T and dereferenceable optimizations. Dive into discussions on current status, synchronization, declared parameters, and referenceable on entry concepts. Examine function-scoped and globally dereferenceable approaches, Arc drop interactions, and NNIR/FCG/ST considerations. Analyze pointer storage solutions, dereferenceable methods for generics, and unsafe cell implementations. Investigate reference decrements, safe obstructions, and actionable test cases. Consider ergonomics, new type wrappers, and safe projections while pondering the implications of reserving syntactic space for future developments in the Rust programming language.
