mac-sys-info

CLI + Library to get detailed information about your Mac system. Including CPU, Cache (L1, L2, L3), Memory, and more. The library is a wrapper around all information that the $ sysctl -a command outputs on Mac. It gives you structured access to it as well as raw access to all keys obtained from $ sysctl -a.

Usage as Lib or as CLI

As Library

Cargo.toml: toml mac-sys-info = "<insert latest version>" Code: ```rust use macsysinfo::getmacsysinfo; use macsysinfo::generatedsysctl_keys::SysctlKey;

fn main() { // get struct with all information let info = getmacsys_info().unwrap();

// even if IDE shows that the Display trait is missing:
// it is there. It gets implemented during compile time
// by "derive_macro" crate.
println!("{}", info.cpu_info());
println!("{}", info.cpu_info().cache_info());
// ...
println!("CPU @ {} Ghz", info.cpu_info().frequency_ghz());

// IMPORTANT: Raw Access to all SysctlKeys is
// available! Keys are located in enum `SysctlKey`
println!("L3 Cache size extracted manually: {}",
         info.all_keys().get(SysctlKey::HwL3cachesize.name()).unwrap()
);

// Some convenient getters.
println!("L2 Cache Size in KB: {}",
         info.cpu_info().cache_info().l2_cache_size_kb()
);
println!("System has {} GB of RAM", info.mem_info().total_memory_mb())

} ```

Run/install as CLI

$ cargo install mac-sys-info $ mac-sys-info # simple $ mac-sys-info -h # help $ mac-sys-info -c # complex $ mac-sys-info -r # raw

Why another tool?

There is already a popular crate called sys-info, that's true. But it doesn't show information about the size of L1 cache, or cache in general. I need this information for a task I'm working on. Therefore I created this crate. It was also fun and as always I learned new stuff. :)
