Vectorized SliceContains Godbolt for the u32 case: https://rust.godbolt.org/z/exT9xYWGs Unsure about: - Should align_to be used? It didn't seem to matter in my benchmark but maybe I was lucky with alignment? - Should u8/i8 also be implemented? Currently uses memchr (SWAR) Some benchmarks on x86 (contains called on an array with no matches, worst case may be slightly worse): ## Large N  ## Small N 
This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrate with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
