Crate riscfetch_core 

RISC-V system information library

Provides functions to detect and query RISC-V specific system information including ISA extensions, hardware IDs, vector capabilities, and more.

Example

use riscfetch_core::*;

if is_riscv() {
    println!("ISA: {}", get_isa_string());
    println!("Extensions: {}", get_extensions_compact());
}
