Rust 1.100

Rust 1.100.0 has been released on November 12, 2026, featuring the long-awaited stabilization of the never type (!) after 10 years and 5 failed attempts, which represents computations that never return a value and can be coerced into any other type. The release also includes new features such as the Allocator API, DropGuard API, improved Cargo functionality for reporting unused dependencies and reducing cache collisions, and changes the `Infallible` type to be an alias for the never type, though this introduces a breaking change for code in editions prior to 2024.
