Summary
This PR adds the missing symmetric PartialEq implementations that were requested in issue #152830.
Previously, only the 'forward' direction (VecDeque == Vec, VecDeque == &am...

Currently we pick "weird" numbers like 1114112 for None::<char>. While that's not wrong, it's kinda unnatural -- a human wouldn't make that ...

This adds a new type parameter to the Range types:

A low-level virtualization interface for Linux-based systems using WebAssembly - Wasm-Thin-Kernel-Interfaces/WALI

Safe, constant-time, minimal-space-overhead casting between trait objects that share a common root supertrait. A bounded trait graph is one rooted at a single explicitly-declared supertrait; that r...
