    Easy function multiversioning for Rust

    Not sure if it will help you. But this looks like crate you can use

  • llvm-project

    The LLVM Project is a collection of modular and reusable compiler and toolchain technologies. Note: the repository does not accept github pull requests at this moment. Please submit your patches at

    rustc +nightly --print=target-spec-json -Zunstable-options --target $TARGET: Look at the cpu field to tell you what the default CPU is for a particular target. These are LLVM CPU names, which unfortunately do not seem to be documented very well (that I can find). x86-64 appears to be the lowest-common denominator of all x86-64 CPUs ever made. On x86_64-apple-darwin, the default CPU is core2 since that was the first CPU that 64-bit macs used. Feature sets are defined here I believe.

  • Scout APM

    Less time debugging, more time building. Scout APM allows you to find and fix performance issues with no hassle. Now with error monitoring and external services monitoring, Scout is a developer's best friend when it comes to application development.
