yara-rust

Bindings for the Yara library from VirusTotal. Only works with Yara 3.7 for now.

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

Example

The implementation is inspired from yara-python.

let mut yara = Yara::create().unwrap();
let mut compiler = yara.new_compiler().unwrap();
compiler.add_rules_str("rule contains_rust {
  strings:
    $rust = \"rust\" nocase
  condition:
    $rust
}").expect("Should have parsed rule");
let mut 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().find(|r| r.identifier == "contains_rust").is_some());

Features

Support Yara 3.7.
Compile rules from strings or files.
Save and load compiled rules.
Scan byte arrays (&[u8]) or files.

Crate features

By default, this crate use a pre-built bindings file for Yara 3.7, but you can use the feature bindgen to use on-the-fly generated bindings.

TODO

Support other versions of yara.
Remove some unwrap on string conversions (currently this crate assume the rules, meta and namespace identifier are valid Rust's str).
Look at the source code of Yara (or in documentation if specified) to assess thread safety.
Look at the source code of Yara (or in documentation if specified) to see if we can remove some mut in some functions (as Yara::new_compiler and Yara::load_rules).
