Bindings for the Yara library from VirusTotal.

More documentation can be found on the Yara's documentation.


The implementation is inspired from yara-python.

const RULES: &str = r#"
    rule contains_rust {
        $rust = "rust" nocase

fn main() {
    let compiler = Compiler::new().unwrap();
        .expect("Should have parsed rule");
    let rules = compiler.compile_rules()
        .expect("Should have compiled rules");
    let results = rules.scan_mem("I love Rust!".as_bytes(), 5)
        .expect("Should have scanned");
    assert!(results.iter().any(|r| r.identifier == "contains_rust"));


  • Support from Yara v4.1.
  • Compile rules from strings or files.
  • Save and load compiled rules.
  • Scan byte arrays (&[u8]) or files.

Feature flags and Yara linking.

Look at the yara-sys crate documentation for a list of feature flags and how to link to your Yara crate.


  • Remove some unwrap on string conversions (currently this crate assume the rules, meta and namespace identifier are valid Rust's str).
  • Accept AsRef<Path> instead of &str on multiple functions.
  • Implement the scanner API.
  • Add process scanning.
  • Report the warnings to the user.
